Additional input types 'object' and 'array' to allow object data as input

[iFrozenPhoenix]

Is your feature request related to a problem? Please describe.
The current implementation of inputs require one of the types (string, number or bool). This approach does not
allow to pass objects as input data (Double quotes in an string input are disallowed, so the data also cannot be passed as
a json string) .

Describe the solution you'd like
My suggestion is to introduce 2 additional types (object and array). With these types object data could be passed to a
task. Alternatively I would suggest an additional top level element "vars" which allow these kind of inputs.

Describe alternatives you've considered
Writing a template for every possible case.
