Make services migration more reliable

Fix for #2045 . I did not use SQL because its hard to convert SQL fields into json with interpolation and without errors. SO I just improved current migration with next:

* skip validation to prevent exception because of new `template` field in validation
* check column for existance before adding them.
  It should allow people who already failed this migration to re-run ti
* select objects with 500 batch size for better memory usage

Tested on migration from 7.0 to 7.9.0.pre

Improve error messages when file editing fails

Give more specific errors in API responses and web UI flash messages when a file update fails.  See #1479.

Instead of returning false from `Gitlab::Satellite::Files::EditFileAction#commit!` when a `Grit::Git::CommandFailed` error is raised, now `#commit!` raises a different error depending on whether the failure happened during checkout, commit, or push.

@dzaporozhets Please let me know if you want to change the HTTP status codes or the error messages in `Files::UpdateService`

Git Clone btn more apparent

Added a faint background to the button to show that it is in an
active state for the user. White background is often hard to tell
if something is being pushed, so adding a "shadow" makes it a bit
easier to tell.

Fixes #1998
