(Feature): Command line functionality

[AndreiCalazans]

Command line functionality for build step testing.

it would essentially read a file which declares the endpoint to verify and model type expected of the endpoint
example:

endpoint: https://teste.com/teste/rest

result: json

{
    result: boolean,
    error: object
}

endpoint: https://teste.com/teste/rest2

result: json

{
    result: boolean,
    error: object
}


endpoint: https://teste.com/teste/rest3

result: json

{
    result: {
        value: string,
        enums: [string],
    },
    error: object
}

by running X command it would read this file and run the tests, if fails exit at code 0.

Thanks to suggestion of Fuechter.
