crimson/mgr: only pick the addr of the same type

crimson/mgr: only pick the addr of the same type

to avoid the attempts to connect an OSD which is bound to a v2
address to a v1 address of a mgr.

in general, osd is bound to both v1 and v2 addresses, but crimson
msgr does not support multiple bound address at the time of writing, so
to avoid the failures when trying to connect to incompatible addresses,
let's filter out them when connecting to monitor. this change
silence warnings like:

peer_addr_for_me v1:172.21.15.106:60008/0 type doesn't match myaddr
v2:0.0.0.0:6802/26710
