[Feature]: Jaeger UI supports for multi-tenancy

[rim99]

Requirement

Discussed in https://github.com/orgs/jaegertracing/discussions/6187

Problem

Jaeger backend components support multi-tenancy with CLI flag --multi-tenancy.tenants .

Proposal

Can we enable this in Jaeger UI?
So user can choose a specific tenant from a dropdown list

The primary use of multi-tenancy is data isolation such that different tenants cannot see each other's data. That goal is antithetical to having a dropdown in the UI which provides no such protection. There is some support in Jaeger for propagating tenancy information if it comes from the UI queries, which can be achieved by having an authenticating proxy in front of the UI.

TLDR - I don't think tenancy dropdown is a priority, there are many other things that are not fully done for proper multi-tenancy support, such as proper data partitioning in the shared storage.
