Fixed an issue where untrusted_lua_sandbox_requires option was not respected.

The plugin now uses additional components to generate the cache key: request consumer, consumer groups, plugin ID, route ID; callout request method, URL, query params, headers, and body.
Fixed an issue where expressions could not read headers, query, and URI captures via shortcuts of the form $(headers.some_header).
