Part of the mtls feature is implemented in googleapis/python-cloud-core#75, and will be released as version 1.16.0.
This PR adds the mtls feature to bigquery client lib. Note that:
(1) if the python-cloud-core version is < 1.16.0, this PR does nothing, it is backward compatible and won't break any current users.
(2) if the user sets
GOOGLE_API_USE_CLIENT_CERTIFICATEenv var to "true" to trigger mtls, then the PR checks python-cloud-core version. It throws an exception asking the user to bump the version, if the version < 1.16.0. So probably it is a good idea to release python-cloud-core 1.16.0 before merging this PR.
(3) the unit tests work for both python-cloud-core versions, so unit test shouldn't break after the upgrading in the future.
