Bump connection limit to 8192 After merging 2e851a77a09a9fb042f88f5beb87fb2dd1b04127, the labs instances now again primarily connect to seaborgium: It is listed first in ldap.conf and nscld.conf and both NSS and nslcd primarily use the first server and only fall back to the second if the first isn't reachable. Before that patch, the server-side idle timeout kicked in and a client which was e.g. connected to seaborgium reconnected to serpens. As such labs instances essentially connected to serpens and seaborgium round-robin every ten minutes. Grafana showed approx 1.2k connections each. Now seaborgium handles about 2.5k connections and serpens only a few hundred. This only leaves about 1.5k connections until slapd reaches the fd limit again, so bump the connection limit to 8192 to add more margin for possible connection spikes.
