Be able to load a profile from an external package

[sbrunner]

Description

Add the possibility to use a profile shared throw a Python package.

Related Issue

Fix #459.

Motivation and Context

Be able to share a profile between different projects.

How Has This Been Tested?

• I create a package with a profile (https://github.com/sbrunner/prospector-profile-duplicated)
• I created a .prospector.yamlconfiguration file that uses this profile
• Verify that we have:
  • The default configuration
  • The profile configuration (new)
  • The project configuration (from .prospector.yaml file)

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Should add a package to be able to write unit tests?

@Pierre-Sassoulas for me, it's ready to be reviewed, thanks :-)

[Pierre-Sassoulas]

I have a small nitpick, and it looks pretty good imo (I might use this for other packages). I think for this kind of big design decision a review by @carlio is required though.

[sbrunner]

Thanks @Pierre-Sassoulas

All looks good to me :-)

I'd suggest putting a prospector-profile-example project on PyPI too perhaps, to demonstrate how it could be used and to add documentation pointing to it, however that could be a separate PR, I'm happy to merge this now.

[sbrunner]

Thanks for the merge :-)
How should we continue?
I can't create a repository on prospector-profile-example, in the documentation we can also point to the tested profile https://github.com/PyCQA/prospector/tree/master/tests/prospector-profile-test
Is it also possible to have an alpha version on pypi to be able to make test in real condition?

[carlio]

You could test it by using a git dependency instead of pypi, do pip install git+https://github.com/PyCQA/prospector@master or something,

Hi there, I got distracted, sorry about that. Prospector 1.10.0 is on PyPI now with this in it :-)
