Is your feature request related to a problem? Please describe.

Feast is often hard to install alongside other python packages that use google-cloud-core. Specifically, Feast sets an upper-bound on this library (2.0.0), but the latest version is 2.3.1 and many python packages have a lower-bound of 2.0.0 and above.

Describe the solution you'd like

Remove google-cloud-core from the setup.py file (https://github.com/feast-dev/feast/blob/master/setup.py#L87). It's already a sub-dependency of some of the [gcp] packages.

Describe alternatives you've considered

In some cases, we can restrict ourselves to older versions of other packages, but this is not always feasible or recommended.
