new aws_dynamodb_global_secondary_index resource

[raduendv]

Description

Introduces a new optional resources aws_dynamodb_global_resource_index which allows users to use lifecycle.ignore_changes for properties like read_capacity and write_capacity.

Adoption is optional, old aws_dynamodb_table resource works the same. The new resource does not work together with the old global_secondary_index block, one must be chosen over the other.

Users migrating to this new resource must import existing indexes into new resource blocks. Users that change their mind can remove the new resources from state and revert back to old config.

Closes #671
