[vstest/subintf] Add vs test case to validate processing sequence of APPL DB keys

[wendani]

What I did
Crafted a vs test case to validate the processing sequence of VLAN_SUB_INTERFACE keys---Key without ip prefix must be processed prior to those with ip prefix when Port object representing sub port interface has not yet been created. If not this case, user configuration other than vrf_name in CONFIG_DB, such as admin_status, will be ignored in later creating SAI sub port interface, a symptom observed and fixed in #1650.

Why I did it
Fix in #1650 shall pass the vs test case added here.

How I verified it
vs test on test_sub_port_intf_appl_db_proc_seq fails without #1650 fix.

1. Set VLAN_SUB_INTERFACE keys with ip prefix into APPL_DB
2. Allow enough time for IntfsOrch to look into keys with ip prefix (sleep 2 seconds)
3. Set VLAN_SUB_INTERFACE key without ip prefix into APPL_DB
4. Iterate test run on all possible admin_staus values, i.e., up and down, to make sure ASIC_DB sub interface attribute ADMIN_V4_STATE and ADMIN_V6_STATE are set according to user configuration, rather than being agnostic to user configuration as a result of Port object being created by keys with ip prefix.
