Failing over to a partition is more siimilar to failing over to another
datacenter than it is to failing over to a namespace. In a future
release we should update how localities for failover are specified. We
should be able to accept a list of localities which can include both
partition and datacenter.
* Add partition fields to targets like service route destinations
* Update validation to prevent cross-DC + cross-partition references
* Handle partitions when reading config entries for disco chain
* Encode partition in compiled targets
Ember Data requires the usage of unique ID to identify its records in the frontend, and we use a centralized function to do that for all records. There are occasions where it can't make an ID, usually this is a bug our side, but there are occasions where Consul might not be giving us the data needed to make an ID, for example if a Service comes down to us with a blank Name. Whilst this isn't a problem to be fixed in the UI, I thought we could make an improvement here by giving a little more info as to why the UI cannot make a unique ID.
This is currently semi-hidden away in the javascript console, but we could potentially surface this in the UI itself as a larger task. I figured this smaller task could help folks in the meantime if they hit upon this as they might open up the javascript console themselves to see whats up and they'd at least get this extra clue.
Fixes a bug whereby servers present in multiple network areas would be
properly segmented in the Router, but not in the gRPC mirror. This would
lead servers in the current datacenter leaving from a network area
(possibly during the network area's removal) from deleting their own
records that still exist in the standard WAN area.
The gRPC client stack uses the gRPC server tracker to execute all RPCs,
even those targeting members of the current datacenter (which is unlike
the net/rpc stack which has a bypass mechanism).
This would manifest as a gRPC method call never opening a socket because
it would block forever waiting for the current datacenter's pool of
servers to be non-empty.

Given that we do not allow wildcard partitions in intentions, no one ixn
can override the DefaultAllow setting. Only the default ACL policy
applies across all partitions.
This table purposefully does not index by partition/namespace. It's a
global view into all service names.
This table is intended to replace the current serviceListTxn watch in
intentionTopologyTxn. For cross-partition transparent proxying we need
to be able to calculate upstreams from intentions in any partition. This
means that the existing serviceListTxn function is insufficient since
it's scoped to a partition.
Moving away from that function is also beneficial because it watches the
main "services" table, so watchers will wake up when any instance is
registered or deregistered.
