Feature request: use pip extras for kms integration dependencies

[darkvertex]

What sort of feature would you like to see?

tink 1.7.0 was relatively lightweight to install: https://github.com/google/tink/blob/1.7/python/requirements.txt but 1.8.0 with its integrations with GCP and AWS KMS brings a lot of dependencies along with it: https://github.com/tink-crypto/tink-py/blob/5934f47df29666ccadaa5ff4cc2ba626f82bcdf5/requirements.in

Would be really nice if pip "extras" were used in the tink python package so that we could select those as optional dependencies only if we needed them, ie to install them all it'd be something like:

pip install tink tink[gcpkms] tink[awskms]

Have you considered any alternative solutions?

I considered staying in 1.7.0 but a vulnerable protobuf lib is used so I prefer not to.

Hi @darkvertex, the reason for these dependencies is that we have stopped depending on tink-cc-awskms and tink-cc-gcpkms for implementing KMS integrations, and instead use native Python implementations.

Thanks for the suggestions, I'll look into this.

This is now in 1.9.0
