Previously this type was defined in structs, but unlike the other types in structs this type
is not used by RPC requests. By moving it to state we can better indicate that this is not
an API type, but part of the state implementation.
I added this recently without realizing that the method already existed and was named
NamespaceOrEmpty. Replace all calls to GetNamespace with NamespaceOrEmpty or NamespaceOrDefault
as appropriate.
Document that this comparison should roughly match MatchesKey
Only sort by overrideKey or service name, but not both
Add namespace to the sort.
The client side also builds a map of these based on the namespace/node/service key, so the only order
that really matters is the ordering of register/dereigster events.
Refactored out a function that can be used for both the snapshot and stream of events to translate
an event into an appropriate connect event.
Previously terminating gateway events would have used the wrong key in the snapshot, which would have
caused them to be filtered out later on.
Also removed an unused function, and some commented out code.
Health of a terminating gateway instance changes
- Generate an event for creating/destroying this instance of the terminating gateway,
duplicate it for each affected service

These new functional indexers provide a few advantages:
1. enterprise differences can be isolated to a single function (the
indexer function), making code easier to change
2. as a consequence of (1) we no longer need to wrap all the calls to
Txn operations, making code easier to read.
3. by removing reflection we should increase the performance of all
operations.
One important change is in making all the function signatures the same.

An extra boolean return value for SingleIndexer.FromObject is superfluous.
The error value can indicate when the index value could not be created.
By removing this extra return value we can use the same signature for both
indexer functions.
This has the nice properly of a function being usable for both indexing operations.
By using a new pattern for more specific indexes. This allows us to use
the same index for both service checks and node checks. It removes the
abstraction around memdb.Txn operations, and isolates all of the
enterprise differences in a single place (the indexer).
registerSchema creates some indirection which is not necessary in this
case. newDBSchema can call each of the tables.
Enterprise tables can be added from the existing withEnterpriseSchema
shim.
