[Request] Cryostat3 auth proxies should not pass user credentials/tokens to upstreams

[andrewazores]

Describe the feature

https://github.com/openshift/oauth-proxy/

  -pass-access-token: pass OAuth access_token to upstream via X-Forwarded-Access-Token header
  -pass-user-bearer-token: pass OAuth access token received from the client to upstream via X-Forwarded-Access-Token header
  -pass-basic-auth: pass HTTP Basic Auth, X-Forwarded-User and X-Forwarded-Email information to upstream (default true)

https://oauth2-proxy.github.io/oauth2-proxy/configuration/overview

--pass-access-token	bool	pass OAuth access_token to upstream via X-Forwarded-Access-Token header. When used with --set-xauthrequest this adds the X-Auth-Request-Access-Token header to the response	false
--pass-authorization-header	bool	pass OIDC IDToken to upstream via Authorization Bearer header	false
--pass-basic-auth	bool	pass HTTP Basic Auth, X-Forwarded-User, X-Forwarded-Email and X-Forwarded-Preferred-Username information to upstream	true

these flags should be explicitly disabled if the upstreams (Cryostat, Grafana dashboard, storage) do not have a use for them.

Anything other information?
