[DOWNSTEAM-ONLY] Bug 2098562: fix build failure related to VaultTenan…

…tSA.createToken

Pull-Request ceph#99 backported a commit that applies cleanly, but causes a
build failure:

    internal/kms/vault_sa.go:313:12: kms.createToken undefined (type *VaultTenantSA has no field or method createToken)
    internal/kms/vault_sa.go:344:12: undefined: vaultTenantSA

In recent versions, `vaultTenantSA` is used, but release-4.10 is stuck
on the old naming of `VaultTenantSA`. The unexporting was done in
upstream ceph#2750, which includes more changes than what we
want in a backport.
