0.8.0

Thank you, @area42 and @raider444, for your contributions!

Breaking changes

Drop support of Python 3.6.
Recent versions of dependencies (hvac and other dev dependencies) require 3.7 or more, and some have even started to drop 3.7.
I hope it won't hurt many, as Python 3.6 is unsupported since December 2021.
The code hasn't changed yet, so it should still run on 3.6, we don't test it anymore though ^^'

Added

• Support hvac 1.X (relaxed the upper constraint on hvac). Initially proposed by @area42 in #18, I just reapplied the change on top of the new main to avoid conflicts (#23)
• Support providing a custom CA bundle for Vault certificate validation, or skipping SSL validation altogether (#24)

Internal

• Bump all dev dependencies and Actions
