Introduce Cucumber parameter type 'command'

[mvz]

Summary

Introduce Cucumber parameter type 'command' and use it

Details

This introduces a new Cucumber parameter type 'command', matching a string between backticks. It then uses this new parameter types to replace the old regular expression based step definitions. This allows more steps to use the Cucumber Expression syntax.

It also removes the need for python to be installed on of the scenarios that uses these step definitions, to ensure they're properly tested.

Motivation and Context

While working on #894, I noticed that the steps matching output from a particular command could not match against a command including quote characters. This change will make it easier to add an extra step definition to support that case. Update: It turns out matching is possible by using \. The present change is still an improvement, however.

How Has This Been Tested?

I ran the relevant scenarios with the updated step definitions.
