v0.13.3 - "Staying Alive"

This release reduces server load while loading large secrets files.

This release should enable connection reuse on the requests to vault. The support for this was technically already in place, but because all requests were sent simultaneously, no actual reuse was done. The new release limits the number of concurrent requests to 8 by default, which can be overridden using the --max-concurrent-requests option VAULTENV_MAX_CONCURRENT_REQUESTS environment variable. Setting this value to 0 restores the old behaviour.

In addition, minor improvements were made to the Vault response parser.
