What type of PR is this?

/kind bug /kind feature

What this PR does / why we need it:

1. When a container with the same name is edited, the modified container configuration is always updated to the first container with the same name.
2. When a container with the same name is deleted, all containers with the same name are deleted

In addition, duplicate container names are not allowed in the kubernetes, So It is necessary to add duplicate name validation to avoid the operation bug of same container name.
