yamlfile module with yaml_setting type+provider, a la Chris Price’ inifile module / ini_setting type+provider

This is an experimental utility module allowing for more dynamic configuration of the myriad of yaml files used to configure various yaml-configured ruby applications with finer grained control than templates would easily allow.

A rapid prototype provider is included built using Adrien Thebo’s filemapper utility module. It won’t account for comments but it mostly works.

The type interface is probably the hardest part and is largely a design question. The prototype says screw it, K.I.S.S., and assumes hashes are the most common thing to be dealing with for yaml configuration files. As such a pair of resources given as:

yaml_setting { 'example1_1':
  target => '/tmp/example1.yaml',
  key    => 'value/subkey/final',
  value  => ['one', 'two', 'three'],
}
yaml_setting { 'example1_2':
  target => '/tmp/example1.yaml',
  key    => 'value/subkey/other':
  value  => 'string',
}

should result in a file e.g. /tmp/example1.yaml:

value:
  subkey:
    final:
      - one
      - two
      - three
    other: string

Right now the type design doesn't allow for ruby symbols to be used as keys.

There are no tests.
