Support for ignored endpoints

[haffla]

Hey! This adds support for ignoring certain endpoints like status endpoint for example.

So now you can do

config.ignored_endpoints = ['StatusController#main']

It's actually very similar to how it can be done in https://github.com/skylightio/skylight-ruby.

I also added some small improvements which I thought make sense. Basically only

• Cleaning redis before test cases
• Redis set and expire in one command
• use match? instead of ~= (faster)

Hope this is OK.
