Standardisation of how we handle pagination in plural datasources

Details

There are some examples of plural data sources in the provider that handle pagination and don't use client libraries for HTTP requests:

• google_kms_crypto_keys - pagination loop
• google_kms_key_rings - pagination loop
• google_kms_crypto_key_versions - pagination loop
• google_storage_buckets - pagination loop
• google_storage_bucket_objects - pagination loop

We could try and standardise what this code looks like to help with possible generation of plural datasources in future. Standardising what the code looks like could also lead to making a helper function, so that handling pagination is a solved problem.
