v1.1.0

This release adds some new features and fixes a few bugs.

• Added the clean command, allowing easy cleanup of the artifacts biscepter created
• Added the option of specifying the max amount of concurrent running replicas
• Added more exhaustive logging during job starting
• Ensured that changing the Dockerfile for a job doesn't result in biscepter reusing builds of older Dockerfiles for the same job
• Fixed the way the commit offset was calculated for determining the next commit to build
