refactor(buf) refactor protobuf files to standard formatting enforced by Buf v2

[sandersms]

Update/refactor the protobuf files for:

cloud
evpn-gw
k8s (placeholder)
opinetcommon
telco (placeholder)
security

The updates are to align with the standard formatting rules for protobuf definitions that the Buf v2 enforces. The updated can be handled using the "buf format" command. Example command syntax

• buf format --diff -w -> this will format all of the protobufs and show the diff changes along with writing the files
• buf format --diff --path ./security -> this will show a diff of the security protobufs that need to be updated
• buf format --diff -w --path ./security -> this will show the diff and write the updated protobufs for the security api
