Injecting secrets into specific containers

[dmitrytretyakov]

Is your feature request related to a problem? Please describe.
For now, the agent injects secrets into all containers.
As we use Vault for sensitive data it's not good to share secrets between all of the containers in the pod.
For example, I don't want to share admin creds from DB to monitoring tools (e.g. prometheus-exporter)
It increases the chance to compromise a system

Describe the solution you'd like
It would be nice to have a way to limit the list of containers in which are required to be injected.

Hi @dmitrytretyakov thanks for raising the issue! Is this similar to #236? There's also a proposed PR solution for it in #245.
