[CT-680] [Feature] Support for .py files when using file selectors

[leoebfolsom]

Is this your first time opening an issue?

• I have read the expectations for open source contributors

Describe the Feature

dbt should just know that when i say: dbt run -m my_model.sql i mean: dbt run -m my_model

but for .py files, since dbt Python models are gonna happen.

I would edit this code, as well as (I think?) this test.

Describe alternatives you've considered

Life would go on without this feature, but why should we settle for less when a first-time contributor (me) wants to build it.

Who will this benefit?

• Pedram, apparently

• Me, because I'll gain experience by making a small contribution to dbt-core.
• The community, because with my newly gained experience, I'll be able to help with more, and more complex, issues over time.
• There are times when it's easier to include the file extension in the dbt run command. For example, if you're generating the dbt run command from a script, and don't want to bother stripping the file extensions from the list of models you plan to run.

Are you interested in contributing this feature?

I'd like to create the PR, but i'll take any help / suggestions / guidance

Anything else?

• Josh's issue adding file selectors and .sql support.
• Josh's PR solving that issue
• Wherein @jwills suggested, albeit with a winky face, I add support for .py files.
