Allow "az aks get-credentials" to use "--ids" parameter instead of RG and resource name

**Is your feature request related to a problem? Please describe.**
Other Azure CLI commands such as "az resource update --ids" allow you to specify the resource ID instead of separate resource name/RG.

**Describe the solution you'd like**
It would be great to be able to use this functionality with az aks get-credentials (and other az aks commands), for example:

az aks get-credentials --ids
