[simulation mode] Add opportunity to call original function from mock

Enable opportunity to call original function from mock
This is really important to have access to the original object and parameters.

Need to add methods
1 - call original function with original arguments
2 - get list of the original arguments. MuranoPL methods can be defined in Pthod and specific args kwargs can be not provided (just args/kwargs). Need to figure out how it can be managed

3 - implement 'call' YAQL function, that allows to pass expanded list and dictionary as
     function parameters. It's a workaround until * and ** will be supported
     in YAQL.

    `call(funcName, obj, [args], {kwargs})`
