Remove logic around finding a configuration file inside directories

[stsewd]

This should only search for a configuration file on the project's root.

https://github.com/rtfd/readthedocs.org/blob/6261427e662d9c3733568c33f760c5f5a2100c6d/readthedocs/config/config.py#L956-L956

As we can face some weird cases like a third party dependency having a readthedocs.yml file. Also, looks like travis only search for a configuration file on the root. And we have on our docs that we only search on the root.

Ref #4668

Can we still provide a way to specify your conf.py location in the configuration?

Use-case: I have my application in root folder and my docs in docs/ subfolder.
I do not want to have extra files that might interact with my app.

Real world example: https://github.com/wemake-services/wemake-python-styleguide

So, can we have an conf_path (or similar) option in readthedocs.yml?

@sobolevn with our rtd configuration file v2, we have an option to specify the conf.py path (but you still need to put the readthedos.yaml in the root of your project). Right now you can to use the admin panel.

Our v2 will be available soon!

This change has nothing to do with the conf.py file btw, it's about the readthedocs.yml file

Is this issue open because I would like to work on this as my first bug. All the "Good First Issue" have a PR opened for them. Can you help me out?

I think it was closed by #4755. Thanks!

How about allowing a few other candidate locations other than root, like docs/readthedocs.yml as well?
Putting all kinds of config files for different services all in root is quite annoying. Despite they are hidden, they still show up on github.
