Add ESLint rule for blank line at beginning of function scope

[cjihrig]

The rule causes warnings if the blank line is missing. Testing turned up a couple places where the blank line was missing in lab.

👍 Shouldn't we create a single module for all hapi-related rules ? One module per rule seems overkill.

[Marsup]

Also, wouldn't it be better to release it as an ESLint plugin ?

[cjihrig]

This was the only rule that @geek brought to my attention. What else is missing/not natively supported by ESLint?

[Marsup]

There were a few when I first implemented ESLint into lab, maybe it changed. I'll try to put up a list someday.

@cjihrig I love the rule! But can you make it into a plugin so I can use it in other projects (without using cli params) (see eslint/eslint#2180)

[cjihrig]

I'll look into creating a plugin today.

[AdriVanHoudt]

@cjihrig cool thanks!

[cjihrig]

Converted to a plugin

[AdriVanHoudt]

@cjihrig thanks I will definitely use this!

[cjihrig]

👍

@geek I'm not familiar with the release cycle for lab, but when do you think this 5.5.2 will be pushed to npm?
