feat(audit): show trace with HTTP's client_ip , user + trusted proxy

[EdouardVanbelle]

• add support of trusted proxy via CIDR in OXICLOUD_TRUST_PROXY_CIDR env variable (comma separated of CIDR)
  note: OXICLOUD_TRUST_PROXY_HEADERS still possible but a log encourages use of OXICLOUD_TRUST_PROXY_CIDR

• HTTP answers provide the X-Request-ID

• logs: add trace/context with:

  • HTTP's client_ip (X-Forwarded-For if via a trusted proxy)
  • User's ID if logged in
  • show a uniq request id (helps correlation)
  • show the associated path

example of logs:
