Include all plugins for Multus

[jaydeokar]

What type of PR is this?
dependency

Which issue does this PR fix?: Multus operations fail if the plugins are missing

What does this PR do / Why do we need it?:
Multus does not install any plugins as a part of installation and expects these plugins to be present. AMI does not include these plugins today on AL23, so this cause Multus operations to fail starting v1.20.2 where we removed the unnecessary plugins.

Testing done on this change: N/A

Will this PR introduce any new dependencies?: Yes, it adds plugins which aren't directly used by VPC-CNI but by other meta plugins

Will this break upgrades or downgrades? Has updating a running cluster been tested?:
No

Does this change require updates to the CNI daemonset config files to work?: No

Does this PR introduce any user-facing change?: No
