Add Google Cloud Storage backend

[AndreaGiardini]

Hello 👋

I took some time to implement a backend driver for Google Cloud Storage. I've followed the S3 implementation and changed what was needed.

I didn't add any tests yet. Let me know if you have some initial feedback about it.

👏👏👏👏 this is awesome @AndreaGiardini, I'm not a GoogleCloud storage so I'm not sure how to really test this

It might be interesting to other if we could add some notes about the cloud (aws and google) backends somewhere here https://github.com/developmentseed/cogeo-mosaic/blob/master/docs/advanced/backends.md (like link how to create session or account 🤷‍♂️ )

@vincentsarago I added some documentation and tests.

I tried the change myself using the CLI, both uploading and downloading files. Seems to work fine for me.
I've used titiler with this custom version of cogeo-mosaic and indeed I can read private mosaic files (before we had to use public HTTP endpoints).

Would be cool though to have somebody else test it as well.

Let me know if something else is missing

Hey @vincentsarago sorry for pinging again. do you have any updates about this? Can we run the CI?

[vincentsarago]

sorry @AndreaGiardini
Could you please run pre-commit to fix listing issues

pip install -e .["dev"]
pre-commit install
pre-commit run --all-files

🙏

[AndreaGiardini]

@vincentsarago all pre-commit hooks are passing now

[vincentsarago]

thanks @AndreaGiardini
I just pushed a release https://github.com/developmentseed/cogeo-mosaic/blob/master/CHANGES.md#302-2021-07-08
it should be on pypi soon

[AndreaGiardini]

That's great @vincentsarago

Looking forward to seeing this landing on titiler so that we can read mosaic from GCS!

cogeo-mosaic requirement for TiTiler is https://github.com/developmentseed/titiler/blob/master/src/titiler/mosaic/setup.py#L10 so you should be all set now
