OCPP 2.0.1 support (#1381)

* Create different ChargePoint based on subprotocol

This also changes default subprotocol setting from OCPP 1.6 to 1.6 and
2.0.1.

* Don't use CentralSystem from ChargePoint

* Create base class for both OCPP versions

* Move some functions to common ChargePoint class

* Move entire post_connect to base ChargePoint

* Move more boot notification handling to base ChargePoint

* Add to base ChargePoint functions called by api.py

* Split off OCPP part of get_supported_features

* Initial OCPP 2.0.1 support

* Implement get features and connector count for OCPP 2.0.1

* Implement connector status for OCPP 2.0.1

* Configure measurands on charger with OCPP 2.0.1

Also report available measurands to home assistant

* Implement set availability and reboot with OCPP 2.0.1

* Implement trigger status notification with OCPP 2.0.1

* Implement get/set variables with OCPP 2.0.1

* Implement same authorisation logic for OCPP 2.0.1

Same as that used for OCPP 1.6, based on configuration.yaml

* Support transaction measurements with OCPP 2.0.1

* Report charging state from OCPP 2.0.1 to HA

* Report id token from OCPP 2.0.1 transactions to HA

* Implement remote start and remote stop with OCPP 2.0.1

* Implement current limit with OCPP 2.0.1

* Clean up unused imports

* Add common functions to be reused by OCPP 2.0.1 tests

Only use switch and button pressing functions in existing 1.6 tests in
this commit.

* Add simple OCPP 2.0.1 test

Test start-up, remote start and remote stop

* Test realistic transaction with OCPP 2.0.1

* Test get/set variable services

* Test more 2.0.1 calls and services

* Move meter value processing to base ChargePoint

* Reuse OCPP 1.6 meter value logic for 2.0.1

* Round energy consumption to 3 decimal places

Subtracting to floats causes imprecision
