Fix(build): add service dependency to redis for several services * fix unit name: the unit name on Ubuntu is `redis-server.service` * services which need a working redis require both After= and Wants= See the description in the `systemd.unit` man page. 2022-05-30 04:04:50 +08:00			`After=syslog.target network.target freeswitch.service kurento-media-server.service redis-server.service`

build: use FIFO scheduler in bbb-webrtc-sfu bbb-webrtc-sfu (and mediasoup) are running in the CFS scheduler which means it has to compete with (much) lower priority tasks like presentation conversion, recording processing, [...] Since it encompasses an RTC application which also handles audio, it should be _at least_ on the same scheduling policy as FS/bbb-html5 - and that should be safer now with mediasoup which has a lower footprint (and generates lower CPU noise overall). This commit puts bbb-webrtc-sfu in the FIFO scheduling policy (same as bbb-html5). Also bumps bbb-html5 nice level up to 18 and sets SFU to nice 19 (so bbb-html5 has some advantage when push comes to shove). This can be improved further by using per-process priorities in SFU. Ideally we'd want mediasoup audio workers and mcs-core to be the same priority as FS (so higher than bbb-html5), but the rest of them (video/screen workers) to be the same or lower than bbb-html5.
