implement some numbers to prepare to control charging current

[ivanfmartinez]

Add some fields identified on #52 as number to be able to control charging parameters.

Before implementing the real control the proxy must be able to respond to the juicebox without enel x servers responding as #54 .

changing to draft while research continues in #39

@ivanfmartinez I'm going to incorporate some of these changes into #58. As it is a large behind the scenes rewrite, it will likely be easier to put this code in the right new places as opposed to having you sort out the new places to put it later.

I'll clarify the full list here and in #58 of what I incorporated.

@Snuffy2 this callbacks are to be able to send new configuration values do the juicebox faster without waiting for a new message came from juicebox. But if you find another way to do this there is no problem.
