Refactor code to not fetch repos that are explicitly excluded

[MasonEgger]

Currently in the code base we fetch the repositories for a user or an organization with the following respectively

opt := &github.RepositoryListOptions{Type: "all"}
...
var repos, resp, err = client.Repositories.List(ctx, *githubUser, opt)

and

opt := &github.RepositoryListByOrgOptions{Type: "all"}
...
var repos, resp, err = client.Repositories.ListByOrg(ctx, *githubOrg, opt)

And when we want to exclude things such as forks,private, archived or disabled repos we simply pass over them in our evaluation

if *repo.Archived == true {
	loggerWithFields.Info("skipping archived")
	continue
}

if *repo.Disabled == true {
	loggerWithFields.Info("skipping disabled")
	continue
}

if *includeForks == false {
	if *repo.Fork == true {
		loggerWithFields.Info("skipping fork")
		continue
	}
}

if *includePrivate == false {
	if *repo.Private == true {
		loggerWithFields.Info("skipping private")
		continue
	}
}

The GitHub API supports changing the types in the options that are declared above as shown in their documentation https://developer.github.com/v3/repos/#list-repositories-for-the-authenticated-user

This would be a good issue if someone wanted to investigate this and see if they can instead modify the opts variable with the appropriate string to prevent us from getting unnecessary repos.

I worked on this issue and find a few things

ListByOrg is easy to refactor to fetch only appropriate repos thanks to the list-organization-repositories API has useful type values like public, private, and forks. I created PR about this. #27

However List is not because the list-repos-for-user API does not have such type values. Also this API does not provide private repo and this mean include-private flag does not work for user repos.

I think it is good to use list-repositories-for-the authenticated-user API if no username is provided. The go-github library List method uses this API if no username is provided too(https://godoc.org/github.com/google/go-github/github#RepositoriesService.List ).
