[booth] pcs booth sync does not synchronize configuration to other clusters

[jnpkrn]

This especially makes that command useless when degenerate
single node clusters are considered, but nonetheless, the point of
the management tool is to make the typical workflows easy, and
"sync across the clusters" is one such typical use case for multisite
nonetheless -- that's exactly what you want to do with booth sync,
don't you?!

Relevant issue here: #224
Note that the motivation example there already works with the
mechanism of "virtual (booth) IP to cluster mapping", which is
exactly what fits into this picture. Good news is that pcsd listening
on [::]:* by default and, as tested, will gladly serve the requests
coming via a virtual IP introduced even once pcsd got started.

To sync booth configs across cluster, you do pcs booth pull and pcs booth sync, as documented. The documentation clearly says pcs booth sync works just in the local cluster.

The improvement you are proposing is reasonable and we will consider it once pcs has awareness of multiple sites.

Why do you close this issue then?

Also, that composition is borderline impractical & inconvenient,
and for said single node cluster, downright betraying since the
limited (and hence not applicable) usability vs. the expectations
attached to the verb sync as used here (it would be another
story if it was marked sync-within-site right away, apparently).

Certainly, there is a lot to left to be desired, hence this issue,
please keep it open, satisfactory resolution remains to be seen.

Due to time constraints and other priorities, we haven't been able to implement these planned higher level booth commands which would be aware of the whole booth formation and which would be able to operate at a cluster level and booth formation level. For the users to be able to set booth at least somehow, only the node-level commands have been implemented. Those, even if not as comfortable as one may desire, provide a complete set of operations needed for configuring and managing booth.

The plans for the more comfortable booth management are still there. Unfortunately given current developer resources and backlog, it is a "blue-sky" project for now.
