Tim Gross 18fdda6242 vault: fix namespace reset for clients with unset namespace (#23491)
The Vault "logical" API doesn't allow configuring the namespace on a per-request
basis. Instead, it's set on the client. Our `vaultclient` wrapper locks access
to the API client and sets the namespace (and token, if applicable) for each
request, and then resets the namespace and unlocks the API client.

The logic for resetting the namespace incorrectly assumed that if the Vault
configuration didn't set the namespace that it was canonicalized to the
non-empty string `"default"`. This results in the API client's namespace getting
"stuck" whenever a job uses a non-default namespace if the configuration value
is empty. Update the logic to always go back to the configuration, rather than
accepting the "previous" namespace from the caller.

This changeset also removes some long-dead code in the Vault client wrapper.
