i was reading tls module source and got the impression that tls config
file stuff is using sip router general config file mechanism. then i
went to see if there is a capability to include a directory, but
based on the wiki page
http://sip-router.org/wiki/cookbooks/core-cookbook/devel is does not look
like it.
anyway, in my opinion one way or another tls.reload needs to be able to
reload all config files in a given directory. otherwise management of
certs is not convenient.
