Auto generates the values for monitor and admin secret
Secrets and the fsid should be automatically generated.
The included patches do the following:

* Remove hardcoded values
* Generates a UUID for the fsid
* Generates the values for monitor and admin secret.

These values are created at the time the proposal is created.
