Add support for pairing

[postlund]

Should work by using atvremote:

atvremote pair

And then add the remote on the Apple TV. Default pin is 1234 (which
must be correctly entered) and name is "pyatv remote". These settings
can be changed with parameters to atvremote. Currently a pairing
timer is set to 60 seconds, so the process must be finished within
that time.

NOTE: Before merging this, some work must be done with tearing down the webserver and zeroconf after the paring period is done. It currently leaks.

I paired it but when using the login ID a 503 was thrown.

What does the URLs look like?

Try adding 0x in front of the login id. I should make that more clear.

[robbiet480]

All good now. I figured that you were adding the 0x in the code so I hadn't added it myself.

[postlund]

Good 👍 For some reason I decided not to do that. I use a regex to decide if the identifier is a HSGID or pairing-guid, which requires 0x. Then I just pass the id along. Guess it was simple that way.
