Better reporting of "cephadm bootstrap" failure

[smithfarm]

Currently, when "cephadm bootstrap" fails, ceph-salt deploy reports the failure like this:

    admin: [2020-03-06 15:21:46.702005] [admin.octopus.co] [STEP ] [BEGIN] Run cephadm bootstrap

I see two problems with this:

first, why am I seeing the command thrice? (This was a single-node deployment, and even with multiple nodes "cephadm bootstrap" is run only once.)

second, the command is shown with lots of escaped whitespace (\ \\\n, etc.). Could the command be shown all on a single line, without newlines and without whitespace-escaping?
