adding config options for delays and timeouts

[CSdread]

Adds two configuration options:

1. request_timeout which controls the timeout for requests to the bond bridge, this solves the timeout issue on initialization of the accessories on first startup
2. delay_in_seconds which controls the delay between issuing commands through the bond bridge. When there are a lot of shades or accessories in a scene commands can get lost due to quantity in a short period of time.

The defaults keep behavior as it is now, but allows for tuning to make things work. These changes are required for the plugin to function with a Bond Bridge Pro and 24 shades with scenes that contain almost all of those shades.

hi @aarons22 im also running into a closely related issue that can be similarly solved: https://forum.bondhome.io/t/need-to-hold-repeat-rf-signal-for-a-few-seconds/1059

hey @CSdread - thanks for putting this together. I took a look at your code and delay_in_seconds doesn't appear to be used anywhere beyond the config validation. Did you still need that or should it be removed?

to maintain the existing values, you'll need to change this to 10000

Suggested change

	"default": 1000,
