vv0.10.0

v0.10.0 - "Sparkles, cake, sparkles!"

Vaultenv now has support for version 2 of the KV secret engine. This
support is automatic. Vaultenv finds out automatically which version
of the KV secret backend you're using. There is nothing to configure:
this support should be automatic.

Backwards incompatible changes
==============================

To make this automatic detection of the version of your secret engine
possible, `vaultenv` now makes an extra HTTP request. This request goes
to the `/sys/mounts` endpoint.

The purpose is to find out which version of the KV engine you are
running and change the request and response parsing logic accordingly.
Make sure that your security policy allows these requests before
upgrading.
