[STACKED #1228] [ENH] Grpc Coordinator/SysDB (#1229)
a9d654b 
## Description of changes
This PR is stacked on #1228, please TAL at that before this. 

*Summarize the changes made by this PR.*
 - Improvements & Bug fixes
	 - n/a
 - New functionality
	 - Introduced a grpc sysdb implementation.
	 - Migrate the protobufs to support Null vs Presence where needed.
	 - Added minimal protobuf definitions to implement the grpc coordinator
	 - Add a mock grpc sysdb server that reimplements the core functionality in memory for testing.

Will address the following open questions in stacked PRs!
Open questions/issues:
- [x] Collection <> Topic Mapping
          _This requires some thought if we use hashing then we can just map the collection onto a topic and store it. Will we ever want to shard a collection across topics?_
        I don't think this is needed at this moment!
- [x] Topic management moving to sysdb interface 
           _This is conceptually simple, we make topic creation implicitly part of sysdb create collection_
          I address this in #1237 
- [x] We need to move the get_or_create concept into sysdb
          _This is conceptually simple, we just move this logic into sysdb and make it aware of it_
         I address this in #1242

## Test plan
*How are these changes tested?*
I added a mock gRPC server that implements the basic functionality of sysdb with in memory data structures.

We will run the coordinator tests with this impl in the bin/cluster test once the go coordinator service is ready from @Ishiihara
