Support passing extra options to rspec

[louim]

I'd like to be able to use this with Guard, like it's possible with to do with parallel_rspec. However this is not currently possible with because guard passes specific options to rspec. Running guard fails with:

[1] guard(main)>
16:04:03 - INFO - Run all
16:04:03 - INFO - Running all specs
/Users/louim/.asdf/installs/ruby/2.6.8/lib/ruby/gems/2.6.0/gems/turbo_tests-1.2.4/lib/turbo_tests/cli.rb:72:in `run': invalid option: --failure-exit-code (OptionParser::InvalidOption)
	from /Users/louim/.asdf/installs/ruby/2.6.8/lib/ruby/gems/2.6.0/gems/turbo_tests-1.2.4/bin/turbo_tests:11:in `<top (required)>'
	from bin/turbo_tests:29:in `load'

Because turbo_tests choke on the options passed. It would be useful to support possing down options to Rspec via a specific flag.

@louim Thank you, Louis!

--test-options option from parallel_tests is a great idea I overlooked. It will solve #13 too.

Steps to implement it:

• Add opts.on("-o", "--test-options '[OPTIONS]'") to TurboTests::CLI#run like in ParallelTests::CLI#parse_options!
• Pass test options in TurboTests::Runner: .run -> #initialize -> #start_regular_subprocess. Merge test_options with @tags before passing to start_subprocess.

Things to consider:

• Deprecate options: -o, --out FILE and -t, --tag TAG. They can be passed via test-options: --test-options '--tag TAG --tag TAG2 --out rspec.txt'

Help is appreciated.

Would this also resolve something like passing --require spec_helper to rspec? Currently having difficulty loading require 'webmock/rspec' when running turbo_tests.

@OneNeptune Can you please provide a repository with reproduction? We use webmock/rspec without any issues.
