Summary:
Fixes T4802. For context, see T1921.
Originally (in T1921), a developer ran into an issue where rendering `phabricator_form()` with an absolute URI confusingly dropped CSRF tokens, and it wasn't obvious why. This is a security measure, but at the time it wasn't very clear how all the pieces fit together. To make it more clear, we:
# expanded the exception text in developer mode to include a description of this issue; and
# added an exception in developer mode when rendering a form like this.
However, (2) causes some undesirable interactions for file downloads. In particular, if:
- developer mode is on; and
- there's no alternate file domain configured; and
- you try to download a file...
...we produce CDN URIs that are fully-qualified, and you get the exception from (2) above.
This is kind of a mess, and producing fully-qualified CDN URIs in all cases is simple and clear and desirable. To resolve this, just revert (2). We still have the clarification from (1) above and this hasn't caused further issues, so I think that's sufficient. This is a rare issue anyway and not particularly serious or error prone (at worst, a bit confusing and annoying, but hopefully easy to understand and resolve after the changes in (1)).
Test Plan: With develper mode and no alternate file domain, downloaded files from Files.

Summary:
See discussion in D8773. Three small adjustments which should help prevent this kind of issue:
- When queueing followup tasks, hold them on the worker until we finish the task, then queue them only if the work was successful.
- Increase the default lease time from 60 seconds to 2 hours. Although most tasks finish in far fewer than 60 seconds, the daemons are generally stable nowadays and these short leases don't serve much of a purpose. I think they also date from an era where lease expiry and failure were less clearly distinguished.
- Increase the default wait-after-failure from 60 seconds to 5 minutes. This largely dates from the MetaMTA era, where Facebook ran services with high failure rates and it was appropriate to repeatedly hammer them until things went through. In modern infrastructure, such failures are rare.
Test Plan:
- Verified that tasks queued properly after the main task was updated.
- Verified that leases default to 7200 seconds.
- Intentionally failed a task and verified default 300 second wait before retry.
- Removed all default leases shorter than 7200 seconds (there was only one).
- Checked all the wait before retry implementations for anything much shorter than 5 minutes (they all seem reasonable).

Summary:
Recently we see issues with huge commits (branch cuts for www) where people received hundreds of emails for the same commit. By checking all the active and archived tasks related to such commits, I saw the following pattern:
- The commit itself is marked as importStatus = 15 which means all the processing was actually done;
- In archived tasks, I see one PhabricatorRepositorySvnCommitMessageParserWorker, one PhabricatorRepositorySvnCommitChangeParserWorker, followed by many PhabricatorRepositoryCommitHeraldWorker, which means that the PhabricatorRepositoryCommitOwnersWorker (who schedule those herald tasks) was never done;
- PhabricatorRepositoryCommitOwnersWorker is always active (for days) with failureCount = 0;
- In daemon log I see a lot of lease expire exception for PhabricatorRepositoryCommitOwnersWorker.
So to me it looks like the following happened:
- Everything is fine until we schedule the PhabricatorRepositoryCommitOwnersWorker
- PhabricatorRepositoryCommitOwnersWorker actually successfully finished but its running time exceed 60s. Before it finishes, it scheduled the PhabricatorRepositoryCommitHeraldWorker task
- When we try to archive it, the lease expiration exception happened. As a result, it stayed active and will be picked up immediately since it is in the head of the queue
- The two steps above repeat forever until we kill it
I am not sure why we want to check lease expiration when we are archiving the task. For now I am giving the worker a little more time since parsing half million affected path needs some time..
Test Plan: Patched in our production and it worked.

This query is unusual (it requires changesets, and does not accept IDs). This keeps us from having to load changeset -> diff -> revision in order to do policy checks. We could also fix this with smarter policy checks and caching, but I'd rather not open that can of worms for now. This object is very low level and relatively unusual, and this small deviation from convention seems like the cleanest cut to make to keep this from snowballing.

We give fewer points for logged in requests. We could futher refine this (more points for a 404, more points for a really slow page, etc.) but let's start simply.
