MT#8773 [CARRIER] add sp2 commands. Use no-sync-db on sp1 commit

Copy relevant sp2 commands from modify network.yml
PRO section that will be skipped later.

Don't try to connect to db, on CARRIER nodes the
config is already pointing to db1a and that node
could be not even created. This will reduce,
installation time due to ngcpcfg timeouts.
