MeshService deeper integration

[lahabana]

Description

Policy attachment/inspect api should be usable from the GUI.

MeshGlobalService (or whatever this related to). MeshHostnameGenerator and other things like this.

TODO complete this issue with precise things to integrate with @jakubdyszkiewicz and @michaelbeaumont

[michaelbeaumont]

• Service view - select services by type
  • Dropdown selector for service type
  • OR button per service type
• Hostname generator view
  • We will already have this accessible from MeshService via status
  • Maybe we can show the same list in every Mesh
    • OR we add a new left-level entry for HostnameGenerators

[jakubdyszkiewicz]

Triage: another option is to just not show HostnameGenerator at all

Not super clear what (if anything) is to be done here at this point in time.

#2469 is covering basic list/summary/detail and covers this part of @michaelbeaumont s comment above:

Service view - select services by type
Dropdown selector for service type
OR button per service type

(we went for button per service type)

I think

• Policy attachment/inspect api should be usable from the GUI.
• MeshHostnameGenerator and other things like this.

Are still work in progress from the backends perspective, and could be better to close this issue and create two new ones for these two points once its clear what's to be done.
