* Unused pylint suppression cleanups
* Remove outdated pylint bug references
* Add flake8-noqa config and note to run it every now and then
* Add codes to noqa's
* Unused noqa cleanups
* Do not require admin account for foscam cameras.
Foscam cameras require admin account for getting the MAC address,
requiring an admin account in the integration is not desirable as
an operator one is good enough (and a good practice).
Old entries using the MAC address as unique_id are migrated to the
new unique_id format so everything is consistent.
Also fixed unhandled invalid responses from the camera in the
config flow process.
* Make RTSP port configurable again as some cameras reports wrong port
* Remove periods from new log lines
* Set new Config Flow version to 2 and adjust the entity migration
* Create a proper error message for the InvalidResponse exception
* Change crafted unique_id to use entry_id in the entity
* Abort if same host and port is already configured
* Fix entry tracking to use entry_id instead of unique_id
* Remove unique_id from mocked config entry in tests
