Daemons - add status of environment to daemon console, etc

Summary: Shows the UI everywhere. Also asort() the keys before calculating the environment hash as that is probably an issue for someone at some point we just don't need to have. Ref T5968.

Test Plan: Viewed the setup check and saw a link to the daemon console. Viewed the daemon console and saw the various stale config daemons. Clicked a daemon and saw a "stale config" header icon where expected. Restarted daemons and all of this went away.

Daemons - better handle rogue daemons from phd

Summary: Ref T2374. While building D10367 I noticed that phd was finding rogue daemons way more than it should be. Re-jigger this code path so rogue daemons are checked for *after* we've dealt with known daemons. This keeps the logic pretty simple overall.

Test Plan: phd start; kill pid files; phd stop and get the right warning; phd stop --force and it kills the rogue demons. phd stop in normal conditions no longer reporting rogue daemons erroneously

Prevent crash when build step has been deleted on build plan

Summary: This prevents crashes when looking at builds, where the build steps have been deleted on the build plan since the build was run.  Currently the only information that's pulled from the build step is the description (because this was too large to copy to every target).

Test Plan: Tested it locally.

Prevent artifact key collision when builds are restarted

Summary: Ref T1049.  Because we no longer destroy artifacts when builds are restarted, we need the build generation number to be part of the artifact key, otherwise we get collisions when restarting builds that contain build steps that emit artifacts.

Test Plan: Ran it with a build plan of "Lease Host" and "Run Command", no longer got an artifact key crash.

Hide "Warning: Permanently added ... to the list of known hosts." in Harbormaster

Summary: Ref T1049.  This messages is always printed to standard error now that the known hosts file is set to /dev/null.  This hides the warning so that we'll be able to parse stderr for Windows hosts (where Powershell decides to output XML...)

Test Plan: Tested locally and verified the warning no longer appears.

Allow pre-commit adapter to use custom actions

Prevent "Wait for Build Commits" from creating billions of logs

Summary:
Resolves T5987.  This build step was at some point converted to use yielding, which meant that whenever the build step executes it will create a new log.  This checks to see if there is an existing log before creating a new one and uses that instead.

Long term we're going to need some way of attaching data to `PhabricatorWorkerYieldException` that can be read when the build step starts again; this will allow us to move more build steps off `while (...) { ... sleep(X); }` loops and onto yielding.

Test Plan: Tested locally.
