What type of PR is this?

/kind bug

Any specific area of the project related to this PR?

/area engine

What this PR does / why we need it:

open_params is read from the falco YAML configuration file and parsed using Go's URL.

For example:
https://github.com/falcosecurity/plugins/blob/c349be6e84d2230698b5ca5d51ddadcda42c5e21/plugins/k8saudit/pkg/k8saudit/source.go#L41-L42

Go's URL parser does not handle whitespace, so if a user defines the open_params in the falco configuration file as follows

open_params: >
/file/path

the parser returns an error. To avoid this, we now trim this parameter so no whitespace will be left for Go's URL parser to error out on.

Which issue(s) this PR fixes:

It doesn't fix it but it started from falcosecurity/plugins#182.

Special notes for your reviewer:

Read falcosecurity/plugins#182.

Does this PR introduce a user-facing change?:

update(falco.yaml): `open_params` under plugins configuration is now trimmed from surrounding whitespace

Go's URL parser does not handle whitespace, so if a user defines the `open_params` in the falco configuration file as follows

```yaml
open_params: >

the parser returns an error. To avoid this, we now trim this parameter so no whitespace will be left for Go's URL parser to error out on.
