Uses github.com/libopenstorage/secrets to communicate with Vault. This removes the need for maintaining our own limited Vault APIs. By adding the new dependency, several other packages got updated in the process. Unused indirect dependencies have been removed from go.mod. Signed-off-by: Niels de Vos <ndevos@redhat.com>
