Scope

When connected to a LoadBalanced cluster:

• Add loadBalanced to the handshake.
• Reject server connections that do not include loadBalanced in the reply.

Not in scope

• Connection pinning to cursors or transactions. Rationale: The C driver does not implement a CMAP compliant connection pool (see CDRIVER-2871). Only one connection is available to a server for all operations within a client.
• Connection tracking.
