[hdpowerview] Support SDDP addon suggestion finder

[andrewfg]

The HDPowerview Hub can be discovered via SDDP. This PR adds support for that.

Depends on openhab/openhab-core#4237

@jlaur for info.

Notes:

1. Strictly this PR is not really necessary since the addon is already suggested vis mDNS. However it helps me to provide a live test case for New SDDP service for addon discovery and thing discovery openhab-core#4237

2. We could eventually add a SddpDiscoveryParticipant component to the binding for discovering the respective Bridge Thing as well.

LGTM

@jlaur just for info: I may have to revert this PR. From my testing of openhab/openhab-core#4237 it looks like the HD PowerView hub does send SDDP Alive notifications, but does not respond to SDDP Search requests. So it may be a) that the HD implementation of SDDP is broken. However it may be b) that my implementation of the core PR is broken. So we will need to get further feedback from other snapshot users to determine if it is a) or b).

Perhaps @mlobstein can help by testing your core PR with #16794?

It the core PR ready to be built and tested? I am working on implementing SddpDiscoveryParticipant for epsonprojecor. The code is straight forward but needs to be exercised. I only have one device that supports SDDP, a Pana DP-UB9000, so testing will be improvised :)

@jlaur just for info, the discovery in the core PR is now fixed (link below) so the HD PowerView Hub is now discovered perfectly..
