Make ephemeral storage of Agent sidecar injector configurable.

[krishnadas-m]

Is your feature request related to a problem? Please describe.
It is observed that the vault agent sidecar gets evicted due to the limit of ephemeral storage. It is currently defaulted to 128Mi and is not configurable via Helm-chart.

Describe the solution you'd like
If we can modify the injector-deployment template to template the AGENT_INJECT_EPHEMERAL_LIMIT value from values.yaml

Describe alternatives you've considered
We need to add/modify annotation on components to increase the limit which can be easily solved if we add the above mentioned capability on the vault helm-chart.

Hi @krishnadas-m, this can be set via the helm chart currently with the injector.extraEnvironmentVars option.

The next release of vault-k8s will also stop setting a default ephemeral storage limit.
