* junos_linkagg implementation and junos modules refactor

*  junos_linkagg implementation
*  junos_linkagg integration test
*  net_linkagg integration test for junos
*  decouple `load_config` and `commit` operations,
   to allow single commit (in case on confirm commit) and
   to perform batch commit (multiple `load_config` followed by single
   `commit`)
*  Other related refactor

* Fix CI issues

* Fix unit test failure
