Adds a flag to allow ifaces and L2s to be ignored. This is so that applictions have better control over what ifaces they want connectivity management for. Enabling the flag forces conn_mgr to consider the iface unready. Also increase NET_CONNECTION_MANAGER_PRIORITY default value from 0 to 1 so that applications can register SYS_INIT callbacks that fire just before conn_mgr initializes. This allows ignored ifaces to be configured before conn_mgr starts, if needed. Signed-off-by: Georges Oates_Larsen <georges.larsen@nordicsemi.no>
