rename module to make it easily discoverable

[ssbarnea]

Bases on an IRC discussion we had on #ansible-devel it was suggested to rename the module to make it easy for users to use it, especially as we aim to make it an ansible core module.

Proposals so far:

• yaml
• yaml_file - similar to ini_file, only downside is that it will be an issue if we ever want to add support for "content" as alternative to "src" as calling parameter.

Someone noted that JSON support could be wanted in the future and that the module could do both. Still, I think that this is outside the current scope and even if we endup implementing that we could create a module alias that does that for json, so we can reuse the codebase.

Please comment with your suggestions/votes.

yaml_file seems right.

This should also become an ansible collection, making much easier for others to use it.
