Make code more generic to handle different SCM types

[svidhani]

Description

Currently there is if else condition to check for SCM type which is very specific.

The code needs to be improved to handle different SCM types more generically which can handle bitbucket, gitlab, github, etc by importing different modules based on scmTypes as shown below
Here I am following convention to define objects keys and the files to make my code flexible.

function(scmType) {
const scmTypes = {
'default': require('./defaultSCM'),
[scmType]: require(./${scmType})
};

     try {
        scmTypes[scmType]();
    } catch(ex) {
        console.log(ex);
        scmTypes['default']();
    }
}
