Vault doesn't generate these, but in some cases Go's internal HTTP
handler does. For instance, during a mount-tune command, finishing the
mount path with / (as in secret/) would cause the final URL path to
contain .../mounts/secret//tune. The double slash would trigger this
behavior in Go's handler and generate a 301. Since Vault generates 307s,
this would cause the client to think that everything was okay when in
fact nothing had happened.
marshalled into JSON or displayed from the CLI depending on the output
mode. This allows conferring information such as "no such policy exists"
when creating a token -- not an error, but something the user should be
aware of.

You can now turn on and off the lease behavior in the generic backend by
using one of two factories. Core uses the normal one if it's not already
set, so unit tests can use the custom one and all stay working.
This also adds logic into core to check, when the response is coming
from a generic backend, whether that backend has leases enabled. This
adds some slight overhead.
fields in 'lookup-self'. Importantly, this also makes credential
backends use the SystemView per-backend TTL values and fixes unit tests
to expect this.
Fully fixes#527
In order to implement this efficiently, I have introduced the concept of
"singleton" backends -- currently, 'sys' and 'cubbyhole'. There isn't
much reason to allow sys to be mounted at multiple places, and there
isn't much reason you'd need multiple per-token storage areas. By
restricting it to just one, I can store that particular mount instead of
iterating through them in order to call the appropriate revoke function.
Additionally, because revocation on the backend needs to be triggered by
the token store, the token store's salt is kept in the router and
client tokens going to the cubbyhole backend are double-salted by the
router. This allows the token store to drive when revocation happens
using its salted tokens.
return a descriptive error indicating that the Secret cannot be returned
because when the token was revoked the secret was too. This prevents
confusion where credentials come back but cannot be used.
