mod_http_oauth2: Add option for specifying TTL of registered clients
Meant to simplify configuration, since TTL vs ignoring expiration is
expected to be the main thing one would want to configure.
Unsure what the implications of having unlimited lifetime of clients
are, given no way to revoke them currently, short of rotating the
signing secret.
On one hand, it would be annoying to have the client expire.
On the other hand, it is trivial to re-register it.
