feat(filtering): Open + Download Job's Trace logs

[azachar]

Hi there,

this is a WIP PR preview of trace log downloading and filtering.
I have added a dialog and some fancy features to operate on a daily basis with GitLab's logs.
So if you run some protractor tests that you need to examine, this should help a lot.

Here is a list of some features:
opens: GitLab page for pipelines, pipeline or job
downloads: trace log, all failed trace logs
filter: based on your domain package your failed stack traces (you need to install additional package for enabling this)
editor: support opening log with an ANSI editor that allows custom filtering
key bindings: to open GitLab's pipelines page and the job selector (ctrl+alt+g) and (shift+ctrl+alt+g)

Unfortunately, download progress is not shown yet. But perhaps some nice contributors could extend this and polish. Also, tests are missing.

Currently, some features are borrowed from additional 2 packages that need to be installed, otherwise filtering will not work that nicely. All is in mentioned in readme.

Hope to hear some feedback from you.

Cheers,
Andrej

Please split your PR in several smaller ones and avoid referencing your packages directly. An user installing gitlab-integration should be able to use it without cloning from github.

Given the size of this merge request, I did not have time to review it all. Please be patient.

Well, It really becomes an epic, I agree :). So take your time. As being said it is a preview, an experiment. I am just testing what suites my needs perhaps you can pick it up and bring it to the next level. I am sure that features like caching and data model needs to be completely rewritten. But for now it "works for me" and it already brings a lot of things such us pipeline selector for all pipelines, statistics to find out which jobs are problematic and so on... Have a look yourself :)
