WIP: first pass at github failure exporter

https://github.com/konveyor/pelorus/issues/456


todo: add documentation
todo: figure out if other labels are required
todo: perhaps more tests

required config was lost in rebase

fix lint, test issues, add doc

rip out my custom config in the ConfigMap

first round of code corrections post review

fix get_app_name to use list comprehension

update configmap doc to allow for a yaml list

This will allow to check exporter pod statuses in easy way, ensure
pods are not occupying cluster resources when they fail.

update tests and PROJECT lists

update the example for failure project config

ensure app labels work as they do w/ jira

raise the exception if TOKEN is invalid
