name updates

a manual port value can be passed to the security agent when needed

update description for security.applicationinfo.port

- introduce NewRelic::Control::SecurityInterface singleton class
- leverage the singleton class to ensure the security agent is only ever
  initialized once
- leverage the singleton class to defer security agent initialization in
  lockstep with dependency detection deference
- have each singleton class perform its own `require` of the singleton
  library so that it's not necessary to understand that the library is
  coming in from the `Control` class that might seem to have nothing to
  do with the singleton class

- update NewRelic::Control::Security source file with license header and
  frozen string literal magic comment
- remove commented out dev dependency from gemspec, as Gemfile will be
  used

NewRelic::Control::SecurityInterface

remove blank line left over from testing to cut down on diff noise

initialize the instance vars

SecurityInterface: Ruby <= 2.4 compatibility

make sure the SecurityInterface singleton behaves as expected

Integration of Newrelic Ruby Security agent

Add newrelic_security gem to changelog

Previously, config descriptions were edited to adhere to a 120 character
line length.

This caused problems for some descriptions when the newrelic.yml file
was generated.

The newrelic.yml task handles its own line lengths.
We should revisit this another time.

Revert spacing changes

* Add Security Agent to config.rake

Add security agent content back to newrelic.yml
