Remove @BetaApi decorator for ordering

[anguillanneuf]

Some APIs for ordering are still tagged as @BetaApi but should be removed now?

java-pubsub/google-cloud-pubsub/src/main/java/com/google/cloud/pubsub/v1/Publisher.java

Lines 320 to 321 in eaeedd8

	@BetaApi("Ordering is not yet fully supported and requires special project enablements.")
	public void resumePublish(String key) {

java-pubsub/google-cloud-pubsub/src/main/java/com/google/cloud/pubsub/v1/Publisher.java

Lines 803 to 804 in eaeedd8

	@BetaApi("Ordering is not yet fully supported and requires special project enablements.")
	public Builder setEnableMessageOrdering(boolean enableMessageOrdering) {

Cleaned up. Closing issue.

Strangely enough I still see this. Can we keep this open until these decorators are fully removed?

I mistakenly thought that I had cleaned this up previously.

Just put a PR together to fix this (linked above). Will close after the PR is merged in.

Merged PR that removes this annotation. Closing
