wip consensus: add RPC to replicate a NO_OP
This patch adds an RPC to replicate a NO_OP message. Unlike NO_OPs that
get sent following leader elections, these NO_OPs do not have any
guarantees regarding the monotonicity of their timestamps with respect
to other operations.
In addition to being a nice tool to check that consensus is running on a
given server for a given tablet, this endpoint is useful in stressing
the assignment of timestamps for non-txn operations. Pinging consensus
on a leader will replicate
It's important to be able to determine whether or not a NO_OP message
was created using this endpoint directly, vs through the normal flow of
Raft's election algorithm, as timestamps assigned in the former are
serialized with respect to writes in the term the NO_OP was sent. As
such, a field has been added to the NoOpRequestPB indicating whether the
NO_OP was sent via this RPC or not.
WIP: would like to add more targetted testing
