Refactoring of the agentpb package.
First move the whole thing to the top-level proto package name.
Secondly change some things around internally to have sub-packages.
# Conflicts:
# agent/consul/state/acl.go
# agent/consul/state/acl_test.go
In a previous PR I made it so that we had interfaces that would work enough to allow blockingQueries to work. However to complete this we need all fields to be settable and gettable.
Notes:
• If Go ever gets contracts/generics then we could get rid of all the Getters/Setters
• protoc / protoc-gen-gogo are going to generate all the getters for us.
• I copied all the getters/setters from the protobuf funcs into agent/structs/protobuf_compat.go
• Also added JSON marshaling funcs that use jsonpb for protobuf types.
