[marcoreni]

Work continues on #4990

Changes proposed in this pull request:

• New resource aws_pinpoint_gcm_channel with related docs and acceptance tests

Output from acceptance testing:

$ make testacc TEST=./aws TESTARGS='-run=TestAccAWSPinpointGCMChannel'
==> Checking that code complies with gofmt requirements...
TF_ACC=1 go test ./aws -v -run=TestAccAWSPinpointGCMChannel -timeout 120m
=== RUN   TestAccAWSPinpointGCMChannel_basic
--- PASS: TestAccAWSPinpointGCMChannel_basic (18.88s)
PASS
ok      github.com/terraform-providers/terraform-provider-aws/aws       20.085s

NOTES:

1. I recycled env GCM_API_KEY since it was already defined in other tests and name suggested it to be generic. Test is skipped if env is missing
2. api_key is ignored during import since the SDK never returns it.

LGTM based on the other similar resources and submitted acceptance testing output (I don't think we should hold this up on getting our own GCM API key). Thanks, @marcoreni! 🚀
