mozci 0.5.0 released - Store password in keyring, prevent corrupted data, progress bar and many small improvements

In this release we have many small improvements that help with issues we have found.

The main improvement is that we now don't store credentials in plain-text (sorry!) but use keyring to store it encrypted.

We also prevent partially downloading any data (corrupted data) and added progress bar to downloads.

Congrats to @chmanchester as our latest contributor!
Our usual and very appreciated contributions are by @adusca @jmaher and @vaibhavmagarwal

Minor improvements:

• Lots of test changes and increased coverage
• Do not use the root logger but a mozci logger
• Allow passing custom files to a triggered job
• Work around buildbot status corruptions (Issue 167)
• Allow passing buildernames with lower case and removing trailing spaces (since we sometimes copy/paste from TH)
• Added support to use build a buildername based on trychooser syntax
• Allow passing extra properties when scheduling a job on Buildbot

You can see all changes in here:
0.4.0...0.5.0
