Vault agent command annotation `vault.hashicorp.com/agent-inject-command`

[ckaipf]

Is your feature request related to a problem? Please describe.

The annotation vault.hashicorp.com/agent-inject-command does not fall back to a default (without specified secret name), see here.

Describe the solution you'd like
According to the documentation, I would expect the use of the vault.hashicorp.com/agent-inject-command annotation to be applied to all rendered templates.

Describe alternatives you've considered
I add the annotation to all secrets, which works, but it's not DRY.
