Feature Request: Add API method to get (balance) information for a single channel

[C-Otto]

Background

As far as I know, only the listchannels (https://api.lightning.community/#listchannels) method returns information about the channels' local/remote balance or its active/inactive status. I'd like to have this information just for a single channel.

Similar to #5932.

Your environment

Maybe it helps to extend https://api.lightning.community/#getchaninfo to add more information for local channels?

lncli listchannels | grep -A 5 <channels remote pub_key>

as is now You need parse it out in code as You are using code ? with bbolt ...

i assume You have 240 channels so that is still manageable in load for transport and cpu(parse)

with etcd or PS YMMW

I'd like to also include the issue described in #6582. In addition to balance information, there's no easy way to see whether a channel is active/inactive. The information provided by getchaninfo gives information about a channel being enabled/disaled, which is not the same as active/inactive.
