Set demand control percentage

[Matze2]

This PR is on top of #184.

It also depends on PRs Apollon77/daikin-controller#268 and Apollon77/daikin-controller#269.

For now only change of demand control percentage is supported.

This PR contains one part under discussion because the new writable parameter "maxPower" does not belong to group "control" but to "demandControl". Since all writable parameter names itself are unique it is enough to check with the second namespace and strip it off. The rest of the logic stays the same.

With this PR I could replace the usage of "daikin-cloud.0..climateControl.demandControl.modes.fixed" in my scripts.

G'day, I desperately need this function by the start of the heating season, as Daikin changed the cloud API and removed the option to set demand control. @Apollon77 , what's missing here and @Matze2 do you find the time to add what's needed in order to release the feature? thanks a lot :-)!!

Hi @indie89 ,

there were some comments from @Apollon77 in the corresponding PR of the low-level project (Apollon77/daikin-controller#268).

I remember that I already worked on them but couldn't test anything during summer.

There should be some progress in the next weeks....

Hi @Matze2 ,
thanks for your reply!
As a temporary workaround I implemented the http api call in my blockly script so that I at least can set the demand control percentage according to the outside temperature. So until this PR ist accepted I still have a working power control.
Thanks in advance an have a good week!

Hi @indie89, today I worked on the feedback of @Apollon77 for the "reading" part.
The "reading" is more sensitive since it might break existing adapters that do not have demand control support integrated.
So I hope we make here some steps forward.

The last commit 57ad37b is optional. It changes the info log from

85 Values updated

to

85 Values updated: {"deviceInfo":24,"modelInfo":7,"control":9,"controlInfo":36,"sensorInfo":5,"demandControl":4}

This helped me to check if demand control is supported (demandControl field is shown) and if values get updated (demandControl > 0).
If you don't like it I can remove it from PR.
