Merge-friendly output of command hashes for breeze

We had just one hash generated from all commands in breeze and that
basically meant that when there were two PRs on two different
commands in Breeze, they resulted with merge conflict which
should be solved with `breeze regenerate-command-images`.

This change turns the hash output into a multi-command one - i.e.
each command has its own hash, which will make it much more
merge-friendly - i.e. if two PRs will work on two different commands
the rebase should result with merge rather than conflict.
