Selects! Numbers! Buttons! ... and more ;)

[RustyDust]

Inspired by #74 and spurred on by the recent success with services/actions I had a closer look at how to implement selects, sliders and whatnot. This is the result with some added goodies

Main stuff

You'll now get some new inputs that are shown with the device under the "Configuration" section:

• a "select" entity to switch the operating mode between "manual", "automatic" and "timeofuse" (yes, "expansion" is
  excluded on purpose)
• two sliders to set the "charge" or "discharge" power of in W.
• three buttons to reset either "charge" or "discharge" or both to 0W
  

There's a lot of code added to make those work. Don't despair, I intend to clean that up if possible.

Warning

When using the sliders, buttons and the selector in the developer tools the help text states that there will be no communication with the device. That's not true here. All changes will be sent to the SonnenBatterie immediately.

Candies

• Found and fixed a bug that caused "production_w" (legacy sensor name, new name is "state_prodcution") to not show up in the sensor list under a recognizable name. It was caused by the translation entry being named "state_poduction_w" instead of "state_production". This fix might also fix the problem reported by @whiteman7 in Integration doesn’t update entities #65
• Added some more icons to various sensors, hope you like it
• Added more information to the device info shown on the device screen
  

Under the hood

Coordinator

Completely reworked the coordinator. Instead of passing around the credentials and using different client sessions for every sub-section, the integration now uses one connection to rule them do it all. The central connection object is now passed around in the hass.data[DOMAIN][config_entry.entry_id]["coordinator"]global scope of HA.
Also, to prevent timeouts when querying the SonnenBatterie, the coordinator now automatically reconnects if the last "login" to the SonnenBatterie API is older than 60 seconds.

Services et al.

For better readability and easier maintenance all sub sections are now split out into different files:

• service.py for the services/actions
• button.py for the buttons
• number.py for number inputs/sliders
• sensor.py well, for the sensors, actually that one isn't new
• select.py for the selctors
• entities.py is the central hub that holds all the helper classes for the files above and also contains the base definitions for selects, numbers and buttons

Finally

Have fun ;)

Wow.. nearly a rewrite :)

But.. did we loose Units?

In my Prod-Env it looks like this:

Never mind! Units came back after a few minutes

Never mind! Units came back after a few minutes

To my recollection I didn't change anything there (sensor_list.py) besides some icons. Still wondering why it took some time for them to show up for you. Browser cache?

yepp i think it was browser cache.

as this version ran a few days without errors on my side i'll merge this pr
