Summary:
The documentation is explicit that Git does not pass this flag:
The $GIT_SSH command will be given exactly two arguments: the username@host (or just host) from the URL and the shell command to execute on that remote system.
This isn't true; it does. Accommodate it.
I'll see if I can fix this in the upstream, too.
Test Plan: Ran various `ssh-connect` commands with -p, etc.

Summary: Fixes T4122. Ref T2230. Instead of storing credentials on each repository, store them in Passphrase. This allows easy creation/management of many repositories which share credentials.
Test Plan:
- Upgraded repositories.
- Created and edited repositories.
- Pulled HTTP and SSH repositories.

Summary:
This cleans up some garbage:
- We were specifying environmental variables with `X=y git ...`, but now have `setEnv()` on both `ExecFuture` and `PhutilExecPassthru`. Use `setEnv()`.
- We were specifying the working directory with `(cd %s && git ...)`, but now have `setCWD()` on both `ExecFuture` and `PhutilExecPassthru`. Use `setCWD()`.
- We were specifying the Git credentials with `ssh-agent -c (ssh-add ... && git ...)`. We can do this more cleanly with `GIT_SSH`. Use `GIT_SSH`.
- Since we have to write a script for `GIT_SSH` anyway, use the same script for Subversion and Mercurial.
This fixes two specific issues:
- Previously, we were not able to set `-o StrictHostKeyChecking=no` on Git commands, so the first time you cloned a git repo the daemons would generally prompt you to add `github.com` or whatever to `known_hosts`. Since this was non-interactive, things would mysteriously hang, in effect. With `GIT_SSH`, we can specify the flag, reducing the number of ways things can go wrong.
- This adds `LANG=C`, which probably (?) forces the language to English for all commands. Apparently you need to install special language packs or something, so I don't know that this actually works, but at least two users with non-English languages have claimed it does (see <https://github.com/facebook/arcanist/pull/114> for a similar issue in Arcanist).
At some point in the future I might want to combine the Arcanist code for command execution with the Phabricator code for command execution (they share some stuff like LANG and HGPLAIN). However, credential management is kind of messy, so I'm adopting a "wait and see" approach for now. I expect to split this at least somewhat in the future, for Drydock/Automerge if nothing else.
Also I'm not sure if we use the passthru stuff at all anymore, I may just be able to delete that. I'll check in a future diff.
Test Plan: Browsed and pulled Git, Subversion and Mercurial repositories.
