inclusion filters

You can constrain which examples are run by declaring an inclusion filter. The
most common use case is to focus on a subset of examples as you're focused on
a particular problem.

You can specify metadata using only symbols if you set the
treat_symbols_as_metadata_keys_with_true_values config option to true.

Background
Given
a file named "spec/spec_helper.rb" with: 
RSpec.configure do |c|
  c.filter_run_including :focus => true
end
Scenarios
  1. focus on an example
  2. focus on a group
  3. before/after(:all) hooks in unmatched example group are not run
  4. Use symbols as metadata
focus on an example
Given
a file named "spec/sample_spec.rb" with: 
require "spec_helper"

describe "something" do
  it "does one thing" do
  end

  it "does another thing", :focus => true do
  end
end
When
I run rspec spec/sample_spec.rb --format doc
Then
the output should contain "does another thing"
And
the output should not contain "does one thing"
focus on a group
Given
a file named "spec/sample_spec.rb" with: 
require "spec_helper"

describe "group 1", :focus => true do
  it "group 1 example 1" do
  end

  it "group 1 example 2" do
  end
end

describe "group 2" do
  it "group 2 example 1" do
  end
end
When
I run rspec spec/sample_spec.rb --format doc
Then
the output should contain "group 1 example 1"
And
the output should contain "group 1 example 2"
And
the output should not contain "group 2 example 1"
before/after(:all) hooks in unmatched example group are not run
Given
a file named "spec/before_after_all_inclusion_filter_spec.rb" with: 
require "spec_helper"

describe "group 1", :focus => true do
  before(:all) { puts "before all in focused group" }
  after(:all)  { puts "after all in focused group"  }

  it "group 1 example" do
  end
end

describe "group 2" do
  before(:all) { puts "before all in unfocused group" }
  after(:all)  { puts "after all in unfocused group"  }

  context "context 1" do
    it "group 2 context 1 example 1" do
    end
  end
end
When
I run rspec ./spec/before_after_all_inclusion_filter_spec.rb
Then
the output should contain "before all in focused group"
And
the output should contain "after all in focused group"
And
the output should not contain "before all in unfocused group"
And
the output should not contain "after all in unfocused group"
Use symbols as metadata
Given
a file named "symbols_as_metadata_spec.rb" with: 
RSpec.configure do |c|
  c.treat_symbols_as_metadata_keys_with_true_values = true
  c.filter_run :current_example
end

describe "something" do
  it "does one thing" do
  end

  it "does another thing", :current_example do
  end
end
When
I run rspec symbols_as_metadata_spec.rb --format doc
Then
the output should contain "does another thing"
And
the output should not contain "does one thing"
