When loading rules, parse a required_plugin_versions item that looks
like:
- required_plugin_versions:
- name: cloudtrail
version: 1.0.1
And save it in the engine.
A new method is_plugin_compatible() takes a plugin and version and
returns whether it's compatible with all required_plugin_versions
blocks in all rules files.
In falco, after loading rules and plugins, iterate over the result of
plugin_infos(), calling is_plugin_compatible(), and exiting if any are
not compatible.
Installation
The grammar uses the lpeg parser. For now install it using luarocks:
luarocks install lpeg.
