chore(deps): update requests-oauthlib requirement from ~=0.8 to ~=1.2

[dependabot-preview]

Updates the requirements on requests-oauthlib to permit the latest version.

Changelog

Sourced from requests-oauthlib's changelog.

v1.2.0 (14 January 2019)

• This project now depends on OAuthlib 3.0.0 and above. It does not support versions of OAuthlib before 3.0.0.
• Updated oauth2 tests to use 'sess' for an OAuth2Session instance instead of auth because OAuth2Session objects and methods acceept an auth paramether which is typically an instance of requests.auth.HTTPBasicAuth
• OAuth2Session.fetch_token previously tried to guess how and where to provide "client" and "user" credentials incorrectly. This was incompatible with some OAuth servers and incompatible with breaking changes in oauthlib that seek to correctly provide the client_id. The older implementation also did not raise the correct exceptions when username and password are not present on Legacy clients.
• Avoid automatic netrc authentication for OAuth2Session.

v1.1.0 (9 January 2019)

• Adjusted version specifier for oauthlib dependency: this project is not yet compatible with oauthlib 3.0.0.
• Dropped dependency on nose.
• Minor changes to clean up the code and make it more readable/maintainable.

v1.0.0 (4 June 2018)

• Removed support for Python 2.6 and Python 3.3. This project now supports Python 2.7, and Python 3.4 and above.
• Added several examples to the documentation.
• Added plentymarkets compliance fix.
• Added a token property to OAuth1Session, to match the corresponding token property on OAuth2Session.

v0.8.0 (14 February 2017)

• Added Fitbit compliance fix.
• Fixed an issue where newlines in the response body for the access token request would cause errors when trying to extract the token.
• Fixed an issue introduced in v0.7.0 where users passing auth to several methods would encounter conflicts with the client_id and client_secret-derived auth. The user-supplied auth argument is now used in preference to those options.

v0.7.0 (22 September 2016)

• Allowed OAuth2Session.request to take the client_id and client_secret parameters for the purposes of automatic token refresh, which may need them.

v0.6.2 (12 July 2016)

• Use client_id and client_secret for the Authorization header if provided.
• Allow explicit bypass of the Authorization header by setting auth=False.
• Pass through the proxies kwarg when refreshing tokens.
• Miscellaneous cleanups.

v0.6.1 (19 February 2016)

• Fixed a bug when sending authorization in headers with no username and password present.
• Make sure we clear the session token before obtaining a new one.
• Some improvements to the Slack compliance fix.
• Avoid timing problems around token refresh.
