Merge branch 'master' of https://github.com/chapmanb/cloudbiolinux
Improve documentation in deploy/settings.yaml-sample.
Another deployer settings documentation update and tweak.
Fix for percolator install when coming from bio_proteomics instead of as a  Galaxy tool.
Per Brad's wisdom, replace deployer's custom virtualenv handler stuff stolen from OpenStack Horizon with virtualenv-burrito based virualenv installation. Eliminates need for tools directory and setup.sh.
Create bucket if it doesn't exist when doing multipart upload. Thanks to Dale for report
Rename deploy/pip-requires to deploy/requirements.txt (this name is a little more common).
Add `ssh` action to deployer to quickly ssh into new vm.
Update leiningen target to use latest stable release
Install bio-linux and bio-linux-keyring in minimal edition to bootstrap installs. Thanks to @roryk
Rename deploy setting property cloudbiolinux_flavor to flavor to reflect greater integration. Remove note about it being untested. Add property target to optionally specify install_biolinux target.
Refactor argument processing to remove code duplication. Allow target and flavor to be specified as arguments (this is optional and if present will take precedence of value in settings file).
Tell ssh to ignore hosts file, my OpenStack deployment recycles IPs frequently.
Clean up bx-python install to use pip. Remove custom global python installs from requirements for ngs_pipeline flavor. Thanks to @roryk
Improve default python install command to use pip even with directory checkouts. Reorganize libraries into separate section for ubuntu to include commonly required libraries for next-gen builds
Provide build for novosort multithreaded BAM sort
