SERVER-31061 Add `mongo+srv://` support for URIs.

The shell now supports parsing and handling `mongo+srv://` style URIs,
as part of the DNS Seedlist support.  These URIs require DNS SRV and
TXT record lookups, for extra configuration options.  The shell also
supports a (limited) form of connection-failover -- when initially
connecting to a non-replica-set cluster, the shell will try each
host listed, in order, until a connection can be established.
