Use GUID for summary queries during deployment

[linyguo]

Fix #562

Add GUID for objects.

• during deployment, check if the object has GUID. If it doesn't have a GUID, create a GUID in the annotations
• during reconciliation, use GUID to identify the object summary instead of the name.

TODO:

• add GC for deprecated summary

Let's consider helm chart upgrading path and symphony standalone (which doesn't have mutation webhook).
My idea is,

1. Add guid in mutation webhook.
2. Get summary: if the object has no guid, use name to query, return the first found result.
3. Delete summary: if the object has no guid, use name to query, then delete both.
4. Upsert summary: If no guid, use name to upsert, otherwise use guid.
