Remove from UI ability to set path to log/config files

And also working directory and PID directory.
Remove from UI debug setting

Normal people might want to set verbose, but not debug.
Only have global verbose/debug attributes

We don't need to have per-daemon attributes, especially as the default
is false for both verbose and debug.
Remove from UI ability to choose port for API/registry

People should not need to change this.
Remove attributes to set config/log paths and ports from json and schema

There is really no reason to allow this to be configured (only glance
does this).
Correctly set default attributes in json, not in create_proposal method
Do not expose service user and passwords in UI
