(Give option to) stop strict checking for PLATFORM

[Aephir]

Is your feature request related to a problem? Please describe.
Since most of the total electricity cost is taxes and fees that change dynamically, I created a custom integration that gets the specific taxes and fees (that change based on a few factors) from a Danish electricity monitoring API, to make a sensor with the same general structure as the Nordpool sensor.

However, since the domain (I think this is where the problem is?) is not "nordpool", the ev_smart_charging integration doesn't quite work - the sensor.ev_smart_charging_status keeps having the state "Waiting for new prices" even when tomorrows prices are populated.

It would be great if the checks (in the price_adaptor.py) were only for e.g. attributes of relevant structure (checking the "today", "tomorrow", "raw_today", or "raw_tomorrow").

Describe the solution you'd like
Don't reject price sensors that have the relevant information, but are not in domain: "nordpool". Or, perhaps just have a checkbox during configuration to disable the most stringent checks.

Describe alternatives you've considered
Changing the domain of my integration to "nordpool" or "energidataservice", but this seems to result in some clashes (with the "real" nordpool integration, I suspect), and the integration no longer loads.

This is worth considering, until then check my changes for general overview what fixes are needed to include Your integration:
#322

@Aephir I have made a pre-release v2.0.2-dev1 that should work with your integration, assuming it has "current_price", "raw_today" and "raw_tomorrow" with the same format as the Nordpool integration. Can you test if it works?

[jonasbkarlsson]

@Aephir I checked your integration and noted that you don't have the attribute "current_price", so it will not work.

I will remove the usage of "current_price". Some of the price integration that already are supported don't have it, so it will be easy to fix this for me. So no need to modify your integration, unless you want to.

Part of release v2.1.0.

The ha-electricity-price integration should work now, but I have not been able to test it.

Sorry for the slow response, but initial tests suggests that it works. Thanks a bunch!
