Custom Secret Backends

Vault doesn't currently support the creation of custom secret backends. The primary reason is because we want to ensure the core of Vault is secure before attempting any sort of plug-in system. We're interested in supporting custom secret backends, but don't yet have a clear strategy or timeline to do.

In the mean time, you can use the generic backend to support custom data with custom leases.
