TODO: auto-tune settings based on host resources or metadata service.

Configuration

Users will be created if Heat Metadata is passed in under the 'mysql.create-users' section. For example:

mysql:
  create-users:
    - username: dbuser1
      database: somedb
      userhandle:
        Ref: SomeWaitConditionHandle

This will cause mysql to create the user 'dbuser1' if it does not exist, and grant it all privileges on somedb. It will have a random password generated and passed to the WaitConditionHandle with the key of the username, and password as the data. A password can also be given for the user like this:

mysql:
  create-users:
    - username: dbuser2
      database: somedb
      password: abcdefg12345

If a userhandle is also given with the password, it will be passed to the wait condition handle in the same manner.
