Add BMS BLE integration

[patman15]

Proposed change

This is the PR add support for integrating over 30 different battery management systems (even more battery brands/models). The new integration bms_ble Bluetooth Low Energy (BLE) battery management systems (BMS) that is currently available as HACS integration. The sensors follow a consistent schema, while the BMS themself have a big variance in published data points. I oriented my self on the principles that the NUT integration uses, i.e. consistent data over a wide variety of devices.

• The data is received via local polling over Bluetooth Low Energy with the library aiobmsble with the changelog.
• The manifest of the integration is kept as short as possible, but due to high number of supported devices it's still quite long. Selection of supported devices is done in a second step in the library. Test data ensures the consistency between the two steps.
• If desired, virtual integrations could be added for the most popular devices
