This commit converts meta.ShardInfo.OwnerIDs from a slice of ids
to a slice of objects. This is to support adding statuses for a
shard for a given node. For example, a node may have a shard
assigned to it but it is currently copying the shard and is not
ready to serve data for it.
The old `OwnerIDs` is marked as deprecated, however, the code
still supports loading from older protobuf-encoded data.
This commit adds a requirement that retention policies must
be fully committed. This means that the replication factor
must be set to whatever the node count is in the cluster.
Fixes#2738
This commit adds the meta.RaftStore which can start a single node
cluster and create nodes on the meta.Data internal structure.
