Cilium Feature Proposal

At present, there is no option to display information about the IP cache (ipcache) by CIDR or labels. This necessitates capturing all ipcache information using the "cilium ip list" command and parsing it subsequently. The suggested feature aims to display ipcache information based on CIDR or labels.

Once implemented, users can utilize the cilium ip command as follows:

Usage:
  cilium ip get ( <cidr> |-l <identity labels> ) [flags]

Flags: -h, --help             help for get
  -l, --labels strings   list of labels
  -o, --output string    json| yaml| jsonpath='{}'
  -v, --verbose          Print all fields of ipcache
