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. If no 'database' parameter is supplied, the user will be given access to all databases. 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.

Privileges may be restricted for the user like so:

mysql:
  create-users:
    - username: dbuser2
      database: somedb
      password: abcdefg12345
      privilege: "USAGE, SELECT"
