Adds support for dynamic token acquire via OID Connect auth, and refresh for Hashi Vault keystores backend.
This allows to use Kubernetes based OIDC auth with
v3-operator
out of the box,without need to resort to additional tooling like
vault-agent
.If OIDC parameters are passed instead of static token, the token will be acquired dynamically. Refresh will only happen if, during keystore secrets loading from Vault, previous token acquired via OID Connect is becoming expired and requests start to end up in 403. The fact of token being expired is deduced using
lease duration value received from Hashi Vault, when originally acquiring the token.
