Describe the Bug

It appears that path rules configured through Docker labels are forced into UPPERCASE for some reason, and thusly don't work.

Example:

  whoami:
    image: containous/whoami
    labels:
      - pangolin.proxy-resources.whoami.name=whoami
      - pangolin.proxy-resources.whoami.full-domain=whoami.example.com
      - pangolin.proxy-resources.whoami.protocol=http
      - pangolin.proxy-resources.whoami.auth.sso-enabled=true
      - pangolin.proxy-resources.whoami.auth.sso-roles[0]=Member
      - pangolin.proxy-resources.whoami.targets[0].method=http
      - pangolin.proxy-resources.whoami.targets[0].port=80
      - pangolin.proxy-resources.whoami.rules[0].action=allow
      - pangolin.proxy-resources.whoami.rules[0].match=path
      - pangolin.proxy-resources.whoami.rules[0].value=/test/*
    restart: unless-stopped

Result:

I'm currently on v1.21.1 and unable to update right now, so I'm sorry if this has already been fixed, but I couldn't see any mention in the change logs.

Environment

Pangolin Version: 1.21.1

To Reproduce

See above.

Expected Behavior

See above.
