4f1b950e0d chore(userspace,falco.yaml): rename new config key to driver.kind. 
Moreover, renamed driver kinds to use better naming, and move driver's related
config keys under `driver.$kind`.

Added DEPRECTATION notices on CLI options, and in falco.yaml.

DEPRECATED options (both CLI and config ones) will have priority over the new ones,
to retain compatibility with existing configs.

DEPRECATED options will be dropped in Falco 0.38.

a1d5bb7009 cleanup: remove init in the configuration constructor 
This `init({});` in the falco_configuration constructor is unnecessary
since when we call the action `load_config`, if we don't have a config
file, we will call the same `init` we have just removed. This cleanup
avoids calling `falco_configuration::init` 2 times.

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
