It would be useful to be able to set a timeout on connections created by
back-ldap and back-meta so that idle connections get closed.

The reason for this is that some firewalls silently time out idle TCP sessions.
As a result, if one of these backends is being used to create a relay through
a firewall, it is quite likely to encounter long delays on the first query
after
an idle period.

Timeouts are available on sessions coming into the server. This is a request
for
the same config options to be available on connections initiated by the server.
