Support Vault EE namespaces
Currently the vault integration does not support Vault EE namespaces. Only the vault server URL, role name and auth path can be configured with the variables. It is possible to just prefix the engine's path with the namespace, but it is not possible to specify the namespace for the authentication - it always uses the root namespace.
This change makes the namespace configurable wiht the VAULT_NAMESPACE
variable (similar to how VAULT_SERVER_URL
, VAULT_AUTH_ROLE
and
VAULT_AUTH_PATH
are being used already). It will fall-back to the
root
value in case the variable is not defined by the user.
