…tting init_cfg (sonic-net#2055)

What I did
conn.mod_config(new_cfg) modifies entries which where not changed in new_cfg.
This causes errors when installing/upgrading extension like, because mod_config pushes the same configuration again:

"ERR swss#orchagent: :- addOperation: Vxlan tunnel 'tunnel1' is already exists” in syslog
I made a change so that when setting init configuration for an extension we are not modifying the whole DB.

How I did it
Perform a conn.mod_entry for entries from init configuration of the package.

How to verify it
Run UT. Make sure no errors when installing extension and having vxlan configuration in config db.
