Introduces pinned operations. When SASL bind finishes, we might still have to maintain a link between the client an an upstream for future bind operations if we got a SASL Bind in Progress result code. We zero out the msgids and remember a server-unique identifer on the client and the relevant operation that lets us retrieve that link again. This operation is reclaimed just like anything else when connections drop. Hopefully, this should work for LDAP TXN and VC Exop support with SASL later as well since it allows for many-to-many links to exist.
