v2.8.1

Added

• Update st2 CLI to inspect COLUMNS environment variable first when determining the
  terminal size. Previously this environment variable was checked second last (after trying to
  retrieve terminal size using various OS specific methods and before falling back to the default
  value).

  This approach is more performant and allows user to easily overwrite the default value or value
  returned by the operating system checks - e.g. by running COLUMNS=200 st2 action list.
  (improvement) #4242

Changed

• Update st2client/setup.py file to dynamically load requirements from
  st2client/requirements.txt file. The code works with pip >= 6.0.0, although using pip 9.0.0
  or higher is strongly recommended. (improvement) #4209

• Update st2 CLI to use a more sensible default terminal size for table formatting purposes if
  we are unable to retrieve terminal size using various system-specific approaches.

  Previously we would fall back to a very unfriendly default of 20 columns for a total terminal
  width. This would cause every table column to wrap and make output impossible / hard to read.
  (improvement) #4242
