Round 2: GCP PubSub Receive Adapter

[evankanderson]

Write a receive adapter for the GCP PubSub Events Source implementation. This should include:

1. Deployment to run the receive adapter
2. Manage credentials for reading from a GCP PubSub subscription.
3. Ability to receive events from a PubSub subscription and deliver to the HTTP address of the channel provided by the controller.
4. RBAC roles for any access needed by 1,2.

The receive adapter is in knative/eventing-sources. Specifically here.

1. Deployment to run the receive adapter
2. Manage credentials for reading from a GCP PubSub subscription.
3. Ability to receive events from a PubSub subscription and deliver to the HTTP address of the channel provided by the controller.
4. RBAC roles for any access needed by 1,2.

1. The Deployment creating it is run by the GcpPubSubSource controller.
2. Credentials are read from a secret. Generation of the secret is documented in GcpPubSubSource's sample.
3. Done by the Receive Adapter binary.
   4.The only RBAC needed for the receive adapter itself is access to the secret. The GcpPubSubSource's controller (which creates the receive adapter's Deployment) needs greater permissions, a subset of those in rbac_role.yaml.
