Issue 19612 os router to allow adding interface by port ip (#30409)

Browse Source 
* check if need update for internal port

* validate port ip

* os_router modified in local

* my_os_router.py tested upto port not found

* tested need update

*  default port attached with subnet getting deleted

* update happened with subnet and port id but rerun update=true?

* update working with portid converted subnetid for match checking

* tested and worked

* extra debug commnets cleaned up

* os_router with port ip tested fine

* deleted test files used wq for my development

* interface type changed for backward compatibility

* check if need update for internal port

* restoring requirement.txt which was deleted accidentally

* isinstance instead of type and white space removal

* trailing spaces removal

* multiple space after keyword 379,441

* fail.json interface type and deug msg changes

* test for membership should be 'not in'

- List of subnets to attach to the router internal interface.
- List of subnets to attach to the router internal interface. Default
gateway associated with the subnet will be automatically attached
with the router's internal interface.
In order to provide an ip address different from the default
gateway,parameters are passed as dictionary with keys as network
name or ID(net), subnet name or ID (subnet) and the IP of
port (portip) from the network.
User defined portip is often required when a multiple router need
to be connected to a single subnet for which the default gateway has
been already used.
