[Request] Ability to deploy Cryostat 3 on paths other than the root /

[andrewazores]

Describe the feature

• https://github.com/cryostatio/cryostat/issues/1810
• https://github.com/cryostatio/cryostat/issues/1860

It should be possible to deploy Cryostat behind a proxy or behind a router that places it at a path other than /. For example, deploying Cryostat at http://myproject.example.com/cryostat should work normally - visiting that URL should bring up the web client UI with all normal functionality. Requests like GET http://myproject.example.com/cryostat/api/v3/targets should respond as normal.

This probably involves setting the root-path and ensuring that any links that Cryostat creates referring back to itself (ex. redirect responses) take this into account and/or use relative paths.

Anything other information?

No response

Probably depends on quarkusio/quarkus#13621 .
