Update google-cloud deps to v2

[mik-laj]

Hello,

Google Cloud API Libraries introduced breaking changes in 2.0.0 (https://github.com/googleapis/python-container/blob/master/UPGRADING.md) and they already caused a number of changes. For this reason, we limit all our google-cloud deps to <2.0.0. This limit means our updates will not receive updates, but everything will still work.

We should try to update all operators to use newer versions so that our users can use the newest API features.

You can track progress using this notebook:

I am working on Dataproc package.

If we want users to be able to install backport packages, we should also remember about the limitations that exist in Airflow 1.10 We don't support them anymore, but users can still use them and it would be great if they could use new and old operators at the same time.

    'google-cloud-bigtable>=1.0.0,<2.0.0',
    'google-cloud-container>=0.1.1,<2.0.0',
    'google-cloud-dlp>=0.11.0,<2.0.0',
    'google-cloud-language>=1.1.1,<2.0.0',
    'google-cloud-secret-manager>=0.2.0,<2.0.0',
    'google-cloud-spanner>=1.10.0,<2.0.0',
    'google-cloud-speech>=0.36.3,<2.0.0',
    'google-cloud-storage>=1.16,<2.0.0',
    'google-cloud-texttospeech>=0.4.0,<2',
    'google-cloud-translate>=1.3.3,<2.0.0',
    'google-cloud-videointelligence>=1.7.0,<2.0.0',
    'google-cloud-vision>=0.35.2,<2.0.0',

We can only update these operators when we stop releasing backport packages.

In addition, Backport providers within 1.10.x, will be supported for critical fixes for three months after Airflow 2.0.0 is released.

@michalslowikowski00 @turbaszek Fortunately, Dataproc does not conflict, but other libraries will cause problems.

I added a new column "To update?", which specifies whether we can update this library or rather we should wait until we drop Airflow 1.10 support.
