Services should not be started until metadata exists

[Dan Prince]

All of the OpenStack services appear to be started/restarted multiple times before proper config metadata exists. See the nova-compute log file for example:

I'm not sure yet if this is an os-collect-config issue, Heat related or something else... but this shouldn't be happening. Having services get started before proper config files exist could cause bad "default" things to happen in some cases.

[Steven Hardy (shardy)]

This bug was reported against an old version of TripleO, and may no longer be valid.

Since it was reported before the start of the liberty cycle (and our oldest stable
branch is stable/liberty), I'm marking this incomplete.

Please reopen this (change the status from incomplete) if the bug is still valid
on a current supported (stable/liberty, stable/mitaka or trunk) version of TripleO,
thanks!

Pretty sure this is not happening anymore. Feel free to reopen if it is.
