Evaluate if we can use kStrictlyNotIdempotent instead of kNoRetry in the following cases:

• FindAndModifyCmd::_runCommand (cluster_find_and_modify_cmd.cpp)
• ClusterWriteCmd::commandOpWrite (cluster_write_cmd.cpp)
• ClusterWriteWithoutShardKeyCmd::Invocation::typedRun (cluster_write_without_shard_key_cmd.cpp)
• ClusterWriteWithoutShardKeyCmd::Invocation::explain (cluster_write_without_shard_key_cmd.cpp)
• ClusterQueryWithoutShardKeyCmd::Invokation::typedRun (cluster_query_without_shard_key_cmd.cpp)
• ClusterQueryWithoutShardKeyCmd::Invokation::explain (cluster_query_without_shard_key_cmd.cpp)

There is also cluster_kill_op, but we think it's unlikely we want to retry this command. We should also evaluate if this is the case.
