e4008217b9 Replacing /tmp/gvisor.sock with /run/gvisor.sock
According to the FHS 3.0 (https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03s15.html), transient UNIX-domain sockets should be placed under the directory /run, so this commit updates the implicit value generated by the application.

f9a152b24c refactor(userspace/falco): generalize responsibilities of init_inspector action
Now, the action takes care of inizializing all app inspectors
(just one in capture mode, one for each evt source in live mode), and of
registering and initializing all loaded plugins in the right inspector as needed.
The plugin initialization logic, which also involves the filtercheck list
population and checks, was moved and refactored from the previous
implementation of the load_plugins action.

Now, the action is in charge of loading all plugins and initializing:

- the list of loaded event sources
- the list of loaded plugins and their config

After this action runs, plugins are loaded but not yet initialized.

752c3d8332 update(scripts/falco-driver-loader): minikube environment is now correctly detected
If there is a file in `/etc/VERSION` the script assumes that it is running in a minikube
enviroment. Furthermore the logic in building the `KERNEL_VERSION` has been updated
according to how the kernel and probe modules are saved in the S3 bucket. The kernel version
for the minikube kernels includes also the minikube version.

daba85b61c update(scripts/falco-driver-loader): make some config variables configurable using env variables
When running falco-driver-loader in local we need to set some config variables to meaningful values.
Those variables usually are set by the CI during the image/packages builds. The changes introduced
by this commit allow to set them at start-up time using env variables

0f45cf49db Use enums for rules content item type
Use an enum instead of a string for the item_type aka "parts of a
rules file" field of contexts.

The set of values is mostly defined by the contexts that were already
created. There are a couple of forward-looking values for rule
outputs/macro conditions/etc. that may be useful for later.

7a5a4c32ee Support condition parse errors in rule loading results
In #2098 and #2158, we reworked how rules loading errors/warnings were
returned to provide a richer set of information, including
locations/context for the errors/warnings.

That did *not* include locations within condition expressions,
though. When parsing a condition expression resulted in a
warning/error, the location simply pointed to the condition property
of the rule.

This commit improves this to handle parse errors:

- When libsinsp::filter::parser::parse() throws an exception, use
  get_pos() to get the position within the condition string.
- Add a new context() constructor that takes a filter pos_info instead
  of a YAML::Mark.

Now that positions aren't always related to the location of yaml
nodes, Make up a generic "position" struct for locations and convert
YAML::Mark and parser positions to a position struct.

Also allow a context to contain an alternate content string which is
used to build the snippet. For contexts related to condition strings,
the content is the condition.
