Issue DM-3199: Standardize Qserv install procedure: step 1 build docker container for master/worker instance and development version 
- shmux could be used for parallel ssh (remove Qserv builtin one) - look at "serf and consul" (See Confluence pages) - improve doc: http://www.slac.stanford.edu/exp/lsst/qserv/2015_07/HOW-TO/index.html - run multiple instances/versions of Qserv using different run dir/ports and the same data
