could not use with couchbase:// scheme on custom port

[ingenthr]

cbdinocluster sets up alternate ports (running in docker) and I set up my config to use the supplied connstr. Unfortunately, it didn't work.

➜  couchbase-shell git:(main) ✗ target/debug/cbsh
[WARN] 2024-07-18 12:44:00.659 Using PLAIN authentication for cluster mbp, credentials will sent in plaintext - configure tls to disable this warning
[ERROR] 2024-07-18 12:44:00.659 Couchbase scheme and non-default port detected, http scheme must be used with custom port (management port)

Unfortunately, this is validated at startup, so I couldn't use shell at all even though other configs were valid. Maybe we should validate them at the time of loading a particular environment?

I removed the validation, and that let me start the process. A later failure happened when doing an upsert:

Failed to load cluster config: │ ... │
│ │ │ │ │ error sending request for url (http │ │
│ │ │ │ │ ://192.168.106.3:30433/pools/defaul │ │
│ │ │ │ │ t/b/acm)

So it looks like we need some enhancement to support doing enough bootstrap to get config or get HTTP for retrieving config.
