feat: implement rename action

[rauno56]

Implemented rename action that sets up transform processor with two rules:

• set(attributes["<to>"], attributes["<from>"])
• delete_key(attributes, "<from>")

Very analogous to delete attribute action.

Purposefully missing UI bits, perhaps @alonkeyval can take ownership for that while this is being reviewed and merged.

Example yaml for rename action:

apiVersion: actions.odigos.io/v1alpha1
kind: RenameAttribute
metadata:
  name: ra-9sz8q
  namespace: odigos-system
spec:
  actionName: Rename network attributes
  renames:
    net.peer.address: network.peer.address
    net.local.address: network.local.address
    net.peer.ip: network.peer.address
    net.host.ip: network.local.address
