Motivation
-----------
We recently updating the connection string parsing for couchbase2
to support default to port 18098 when no port specified. The
check that we added was incorrect.

Changes
-------
Update couchbase2 connection string parsing to check for a port value
of -1.

Motivation
==========
A new `function_scope` field was introduced in 7.1 which acts as a namespace or grouping tag. We should support it in the SDK by adding a new scope-level eventing function manager.

Changes
=======
* Add an eventingManagerProvider interface, alongside a core implementation.
* Refactor the existing EventingFunctionManager to use the eventingManagerProvider internally.
* Add a new ScopeEventingFunctionManager to support scoped eventing functions.

Results
=======
All tests pass

Motivation
----------
The initial call to query or search may succeed but, due to how grpc
works, errors like "service not available" might only be surfaced
when reading the first item from the stream. We need to be able
to retry when this happens.

Changes
-------
Update our couchbase2 request path to accept a "peek" callback
which can be used to access the result before leaving the retry
logic, and respond with an error if required.

…load balancing

Motivation
==========
The RFC requires SDKs that implement concurrency for range scan to distribute scans across nodes in the cluster as evenly as possible.

Changes
=======
* Add rangeScanLoadBalancer that handles the distribution of scans across the nodes
* The rangeScanOpManager uses the rangeScanLoadBalancer to decide which vbucket to scan next
* Add Concurrency to ScanOptions

Results
=======
All tests pass (including FIT)

Motivation
----------
Using WaitUntilReady against gocaves is unreliable and sometimes
fails. Investigation into this issue has pointed to it likely
being a bug somewhere in caves itself.

Changes
-------
Mark waituntilready as not supported by mock.
