Fix grdf without captcha, add load into HA LTS

[vingerha]

I used the other PR "Release 1" to add grdf components and load into long-term-statistics
With the recent change of login at GRDF, I reshuffled the code to make it work without the captcha

Issues I had with loading config.json elements. In some cases self.configuration([PARAM]) worked and in others it did not so used configuration_json.get([PARAM]). As this is not just with 'my' code I assume the original py has introduced that....is confusing a lot.
For now use_captha is hard-set to False but I would prefer to have this via the json, same as for allowing to print screenshot.

For me the IDs were changing on each refresh. It may be more stable to rely on input types or input name
I used this for password

            ep = EC.presence_of_element_located(
                (By.XPATH, r"//input[@name='credentials.passcode']")
            )

and this for email

           EC.presence_of_element_located(
                (By.XPATH, r"//input[@name='identifier']")
            )

I have abandoned this and rebuillt gazpar2mqtt as it was too cumbersome to also have Veolia for which I have 0 interest.
