Bug 5530: Build cfgman documentation

[yadij]

Use automake to build the cfgman HTML documentation.
This was done as part of the daily snapshot release
which is no longer happening.

This is an optional output which can be built using:

   make -C doc cfgman

At most, a question I have is why is this target not built automatically?

I considered that, but it is extra build time for everybody+CI and there are not many uses.

That said, we might want to consider making the whole of doc/ an optional build target.

The risk with this choices is that potential users might not know it exists, and it might rot.
How about adding and other doc targets as explicit tests in the "slow" CI? We don't really care about speed there

That said, we might want to consider making the whole of doc/ an optional build target.
Might be worth a (different) discussion
