fix python 3.10 compatibility

[lalmeras]

• vendored requests not compatible with python 3.10
• vendored requests added because of disable pyopenssl for ovh to fix "EPIPE"
  that seems to be fixed by requests 2.11.0
• so vendored requests is dropped and replaced by a adequate requests
  dependency
• all vendored requests references are dropped
• changelog proposal for next version

This is an alternate proposal to handle python 3.10 compatibility. It implements my proposal done on #106 to drop vendored requests as it seems to me that an updated requests library is a better way to fix an pyopenssl pooling issue.

Fix the python 3.10 issue:

envs/py3/lib/python3.10/site-packages/ovh/client.py:49: in <module>
    from .vendor.requests import request, Session
envs/py3/lib/python3.10/site-packages/ovh/vendor/requests/__init__.py:58: in <module>
    from . import utils
envs/py3/lib/python3.10/site-packages/ovh/vendor/requests/utils.py:30: in <module>
    from .cookies import RequestsCookieJar, cookiejar_from_dict
envs/py3/lib/python3.10/site-packages/ovh/vendor/requests/cookies.py:164: in <module>
    class RequestsCookieJar(cookielib.CookieJar, collections.MutableMapping):
E   AttributeError: module 'collections' has no attribute 'MutableMapping'

Hi @rbeuque74 apologies for pinging you directly but since you're one of the maintainers here, I wanted to ask if there is any progress with this PR?

I'm currently in the progress of adding ovh to conda-forge and the vendored requests is making this quite difficult. Additionally, it is missing some bug fixes that are available in newer versions so it would be great if this could be merged?

@rbeuque74 @geoffreybauduin Gentle ping again

[BastianZim]

Thanks @geoffreybauduin If you have the necessary rights, would you mind merging this and making a new release?

[geoffreybauduin]

@BastianZim while I would be happy to move forward and help you fix this issue, you are now in the hands of @rbeuque74 to move forward. I'll contact him and see how we can set this up in the near future.

[BastianZim]

Great, thank you!

Suggested change

# Disable SNI related Warning. The API does not rely on it

I will have to remove that one, as the API do now rely on it.

[BastianZim]

@rbeuque74 Thanks for the review. Does that need to be done in this PR or can this be merged?
Sorry for asking so much, I would just need this PR downstream. :)

[lalmeras]

Il push a new commit to remove comment and SNI warning deactivation.

[geoffreybauduin]

We are currently adapting our CI pipeline, since this repository was still using travis-ci.org, in order to be able to push a new version to pypi.

Once it is setup we will move forward. Sorry for the delay

[rbeuque74]

Setup of the CI pipeline took longer as expected, as we stumble upon a lot of incompatibilities due to build libraries not compatible anymore with Python 2.7, 3.4 and 3.5.
Therefore, I released a v0.6.0 version, that doesn't include Python 3.10 compatibility.
Python 3.10 will come with v1.0.0 that will drop compatibility to Python 2.7, 3.4, 3.5.
