Add nrpe-external-master-relation-joined hook to set the service unit as the primary relation

Add nrpe-external-master-relation-joined hook to set the service unit as the primary relation

This is needed to avoid the race between the main charm and conn-check subordinate in the nrpe relation (nrpe subordinate will pickup the first relation, if none is defined as the primary)
