DRIVERS Ticket Description
We are using DCOS (marathon/mesos) to manage our services. DCOS generates SRV records for our mongos instances under a record that looks like

_mongos-mongodb._tcp.marathon.mesos

However, there's currently no way for me to use this because when I provide a connection url like

mongodb+srv://_mongos-mongodb._tcp.marathon.mesos

the drivers prepend "mongodb._tcp" to the provided url. It's not clear why it's required that the host _must start with "_mongodb._tcp". Why not let the user specify the actual DNS entry to query?

I believe the same issue will exist for multiple orchestration frameworks such as Consul/Nomad and Kubernetes.

Drivers should sync their URI options and seedlist discovery spec tests to this commit. Drivers should accept a new URI option srvServiceName that overrides the default "mongodb" service name for SRV lookup in both discovery and polling.

Documentation Changes: Not Needed
