improvement for rspec testing during TDD dev

Changes to help improve running of rspec tests during dev mode:
1.  cleanup of lots of output being displayed to the console, which made the rake summary hard to read.  
2.  resolve formatter warnings that resulted from prior rspec2 to rspec3 library update
3.  ignore local rspec config so that a .local-rspec config can be locally customized for faster local runs.  Sample recommended local config during dev to fail quickly and exclude integration tests such as spec/bin/compile_spec.rb (which takes a while as it downloads artifacts)
     --fail-fast
     --tag ~integration

Tip:  When debugging/troubleshooting a failed test and display of output is needed, output can be displayed by setting metadata of the test with show_output: 'true' and log_level: 'DEBUG'.
