Put env vars into their own cloud config
The semantics around mixing environment variables and config file values
are confusing at best and no reasonable usecase has been expressed as to
why doing so is desirable.
Move the logic around environment variable processing to always provide
an "envvars" cloud if any envvars are set. The cloud will only exist in
the presence of OS_ env vars.
get_one_cloud() will default to returning the envvars cloud if it
exists.
