[const-cloudinary]

Adds the collections command to run Collections API methods from pycloudinary 1.47.0.

cld collections create_collection "Summer campaign" -o description "Campaign assets"
cld collections add_collection_assets <collection_id> '["<asset_id>"]'
cld collections create_collection_public_page <collection_id>

Brief Summary of Changes

• requirements.txt: cloudinary>=1.47.0 (first version with cloudinary.collections).
• cloudinary_cli/core/collections.py: new collections command, same shape as provisioning. Supports -o, -O, -ls, --save, and -d, which opens https://cloudinary.com/documentation/collections_api.
• cloudinary_cli/utils/utils.py: hide base64url_decode (imported by cloudinary.collections) from -ls.
• README.md, DOCKER.md: document the command.

• No

Reviewer, please note:

• The method names come straight from the SDK, so listing is cld collections collections.
• Works with an API key and secret, or with an OAuth login (cld login).

Checklist:

• My code follows the code style of this project.
• My change requires a change to the documentation.
• I ran the full test suite before pushing the changes and all the tests pass.

Unit tests (excluding the test_modules integration tests) pass locally against pycloudinary 1.47.0. The integration tests were not run locally. All 13 Collections API methods were also run against live clouds, with an API key and with OAuth.
