513f122aff feat: support parsing of system environment variables in yaml 
In order to allow the user to supply environment variables in standard
ways performed in other applications the get_scalar function has been
extended to support defining an environment variable in the format
`${FOO}`. Environment variables can be escaped via defining as `$${FOO}`.
As this handles some additional complexity, a unit test has been  added
to cover this new functionality

eaa4354ddf cleanup(userspace/falco): new consistent metrics output fields classes falco. and scap. 
* Ensure each metric field name more consistently adheres to the grammar used in Falco rules:
  * `falco.`: new field class representing userspace counters, statistics, resource utilization, or necessary information fields
  * `scap.`: new field class represents counters and statistics mostly obtained from Falco's kernel instrumentation before events are sent to userspace, but can include scap userspace stats as well
* minor cleanup
