Fixes T6741. This allows Almanac services to be locked from the CLI. Locked services (and their bindings, interfaces and devices) can not be edited. This serves two similar use cases:
- For normal installs, you can protect cluster configuration from an attacker who compromises an account (or generally harden services which are intended to be difficult to edit).
- For Phacility, we can lock externally-managed instance cluster configuration without having to pull any spooky tricks.

- Locked and unlocked services.
- Verified locking a service locks connected properties, bindings, binding properties, interfaces, devices, and device properties.

Summary:
Ref T5833. This allows services to be typed, to distinguish between different kinds of services. This makes a few things easier:
- It's easier for clients to select the services they're interested in (see note in T5873 about Phacility). This isn't a full-power solution, but gets is some of the way there.
- It's easier to set appropriate permissions around when modifications to the Phabricator cluster are allowed. These service nodes need to be demarcated as special in some way no matter what (see T6741). This also defines a new policy for users who are permitted to create services.
- It's easier to browse/review/understand services.
- Future diffs will allow ServiceTypes to specify more service structure (for example, default properties) to make it easier to configure services correctly. Instead of a free-for-all, you'll get a useful list of things that consumers of the service expect to read.
The "custom" service type allows unstructured/freeform services to be created.
Test Plan:
- Created a new service (and hit error cases).
- Edited an existing service.
- Saw service types on list and detail views.
- Poked around new permission stuff.
- Ran `almanac.queryservices` with service class specification.

Summary:
Ref T5955. Summary of intended changes:
**Improve Granularity of Authorization**: Currently, users have one Conduit Certificate. This isn't very flexible, and means that you can't ever generate an API token with limited permissions or IP block controls (see T6706). This moves toward a world where you can generate multiple tokens, revoke them individually, and assign disparate privileges to them.
**Standardize Token Management**: This moves Conduit to work the same way that sessions, OAuth authorizations, and temporary tokens already work, instead of being this crazy bizarre mess.
**Make Authentication Faster**: Authentication currently requires a handshake (conduit.connect) to establish a session, like the web UI. This is unnecessary from a security point of view and puts an extra round trip in front of all Conduit activity. Essentially no other API anywhere works like this.
**Make Authentication Simpler**: The handshake is complex, and involves deriving hashes. The session is also complex, and creates issues like T4377. Handshake and session management require different inputs.
**Make Token Management Simpler**: The certificate is this huge long thing right now, which is not necessary from a security perspective. There are separate Arcanist handshake tokens, but they have a different set of issues. We can move forward to a token management world where neither of these problems exist.
**Lower Protocol Barrier**: The simplest possible API client is very complex right now. It should be `curl`. Simplifying authentication is a necessary step toward this.
**Unblock T2783**: T2783 is blocked on nodes in the cluster making authenticated API calls to other nodes. This provides a simpler way forward than the handshake mess (or enormous-hack-mess) which would currently be required.
Test Plan:
- Generated tokens.
- Generated tokens for a bot account.
- Terminated tokens (and for a bot account).
- Terminated all tokens (and for a bot account).
- Ran GC and saw it reap all the expired tokens.
NOTE: These tokens can not actually be used to authenticate yet!

- Force-associated a repository with the service using a raw MySQL query.

Ref T5833. Currently, we have an `AlmanacDeviceProperty`, but it doesn't use CustomFields and is specific to devices. Make this more generic:
- Reuse most of the CustomField infrastructure (so we can eventually get easy support for nice editor UIs, etc).
- Make properties more generic so Services, Bindings and Devices can all have them.
The major difference between this implementation and existing CustomField implementations is that all other implementations are application-authoritative: the application code determines what the available list of fields is.
I want Almanac to be a bit more freeform (basically: you can write whatever properties you want, and we'll put nice UIs on them if we have a nice UI available). For example, we might have some sort of "ServiceTemplate" that says "a database binding should usually have the fields 'writable', 'active', 'credential'", which would do things like offer these as options and put a nice UI on them, but you should also be able to write whatever other properties you want and add services without building a specific service template for them.
This involves a little bit of rule bending, but ends up pretty clean. We can adjust CustomField to accommodate this a bit more gracefully later on if it makes sense.

Summary:
Ref T2787. Currently, you add payment providers (Stripe, Paypal, etc) in global configuration.
Generally, this approach is cumbersome, limiting, and often hard for users to figure out. It also doesn't provide a natural way to segment payment receivers or provide web access to administrative payment functions like issuing refunds, canceling orders, etc. I think that stuff definitely needs to be in the web UI, and the rule for access to it can't reasonably just be "all administrators" in a lot of reasonable cases.
The only real advantage is that it prevents an attacker from adjusting settings and pointing something at an account they control. But this attack can be mitigated through notifications, some sort of CLI-only merchant lock, payment accounts being relatively identifiable, etc.
So introduce "merchants", which are basically payable entities. An individual merchant will have attached Paypal, Stripe, etc., accounts, and access rules. When you buy something in an application, the merchant to pay is also specified. They also provide an umbrella for dealing with permissions down the line.
This may get a //little// cumbersome because if there are several merchants your saved card information is not shared across them. I think that will be fine in the normal case (most installs will have only one merchant). Even if it isn't and we leave providers global, I think introducing this is the right call from a web UI / permissions point of view. I'll play around with it in the next couple of diffs and figure out exactly where the line goes.
