refactor(misconf): pass options to Rego scanner as is

[nikpivkin]

Description

Now each configuration scanner accepts Rego scanner specific options and stores them in its fields for subsequent initialization of the Rego scanner. Instead, all Rego-specific options can be passed directly to the Rego scanner. This will make it easier to add new Rego options.
