fix(bbb-webrtc-sfu): add ALLOW_CONFIG_MUTATIONS to service After node-config was bumped to 3.3.9 (from 3.3.6), it started throwing errors if configurations are mutated without the ALLOW_CONFIG_MUTATIONS env var set. We mutate some configs directly, but I every time I added one of those I made sure that they are always deep cloned. However, we hit an issue with kurento-client mutating a config input, which is an indirect mutation. So, to prevent further surprises I'm allowing mutations on production while prohibiting them in dev envs until I'm 100% sure nothing, direct on indirect, improperly mutates configuration values. 2023-03-13 23:20:00 +08:00			`Environment=ALLOW_CONFIG_MUTATIONS=true`
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.
