Update README
Become Spectrometer (Officially)
Fix indentation in test cases
Remove Launchpad - Rely on LDAP ID instead

* Remove all launchpad related code
* Replace launchpad_id with ldap_id
** This is the same as the username in Gerrit
** LDAP scraping will add additional user data
** This fixes the duplicates issues
* Use "get" to avoid KeyError for "releases" in decorators.py
