REST module config options

[James Narey]

Hi,

I'm working on an existing FreeRADIUS 3.0.25 implementation, in particular
the REST module.

The current configuration sets the following config items in the tls block:

cacertdir
cacertfile
verify_cert

These don't appear in the default rest config for 3.0.x. The do appear in
the NetworkRADIUS wiki, though the first two do not have descriptions. This
page's 'Default Config' link goes to the same file - mods-available/rest in
the 3.0.x branch.

I'm unsure which names to be using and, while the names of the top two are
descriptive, it would be helpful to see some documentation before
continuing to rely on them.

It would also be helpful to know whether there is a reason to use
verify_cert vs check_cert, though it is clear at least that these do the
same thing.

Thank you,

Jim.
