When adding a new subscription check for an existing matching one,
considering the source uri hierachy. Deny a new individual
if there is already a sync all subscription, and deny
a new sync all if there is already an invidual one.
After a new sync all subscription is created a set of event messages
are sent to the client containing the initial state of each source
down in the hierarchy. And, every time one of the source states changes
a new message is sent.
Test Plan:
PASS: Build the container images
PASS: Mannually deploy them and test with v2 client
PASS: Create a '/././sync' subscription and check the event messages
PASS: Check current subscription list
PASS: Change GNSS sync state and check the event messages
PASS: Attempt to create a new individual subscription and
check it fails
PASS: Delete the '/././sync' subscription
PASS: Check current subscription list again
