Conditional assertions for more fine-grained logic

[tomas-fp]

New API method:

• grappa.when

if grappa.when(should.be.os('centos')):
    'nginx' | should.be.running
    80 | should.be.listening
    'eth0' | should.have.interface

if not grappa.when(should.be.os('ubuntu')):
    'apache' | should.be.running
    8080 | should.be.listening

if '/opt' | grappa.when(should.path.exists):
    '/opt/foo' | should.directory.exists
    '/opt' | should.have.subdirectories(['log', 'app', 'run'])

Hi @h2non , I wanted to work on it. Can you please tell me how should I approach it?

[h2non]

This is not a trivial feature. Basically, one idea to implement what is on the examples above would be maintaining a global state everytime grappa.when is invoked in order to change the assertions behavior: avoid them to raise an exception, and instead store it internally so grappa.when can evaluate it accordingly. Just an idea anyway.
