Add Rubocop CI (#7083)

* Rename IgnoredPatterns to AllowedPatterns. * Exclude docopt.rb (not our code) from Rubocop * Disable Style/RedundantReturn * Disable Style/MutableConstant * Disable Style/NumericLiterals * Set Layout/IndentationStyle to spaces * Temporarily disable various cops. * Add Rubocop CI via Octocop * Lint tree with rubocop -A -c .rubocop.yml Co-authored-by: Satadru Pramanik <satadru@gmail.com>
