CoreAPI Resource Cache

[MatiWall]

In memory cache used to efficiently map between the singular and plural resource names to api group (and versions)

Should map between

• [x] singular name -> kind
• [x] singular name -> group
• [x] singular -> plural
• [x] plural name -> kind
• [x] pural name -> group
• [x] plural -> singular
