feature(stryker): #336 Configurable tmp folder location

[brunoqueiros]

Ability to specify a different temporary folder instead of .stryker-tmp. Solution based on #475

stryker —tempDir=.another-path-tmp

[nicojs]

I've made some changes. 2 things mainly:

• Changed provideValue to provideClass. With typed-inject's provideValue('temporaryDirectory', TemporaryDirectory) you specify to provide the class itself for the 'temporaryDirectory' token. Using provideClass will instruct typed-inject to instantiate and cash the temp dir.
• Removed the instance() method, since typed-inject will now make sure it is a singleton.

We could still improve on the dependency injection logic. Especially the passing around of the temp dir variable across multiple constructors. But it is already a big improvement.

I didn't update the unit tests or anything, you want to take that? 😅

@nicojs what do you think? ☝️

This isn't needed anymore. typed-inject is now responsible for the disposing of it.

@brunoqueiros I've made some changes. Namely:

• Merge master back into this branch
• Document the tempDirName option in readme and StrykerOptions / Config
• Make unit tests pure unit tests instead of testing integration. I.e. use sinon.createStubInstance(TemporaryDirectory) instead of testInjector.injectClass(TemporaryDirectory) wen not unit testing TemporaryDirectory itself

I will merge it if the build is green. 💚

Sorry it took so long. I was on vacation and didn't get around to looking at this until now. 😥
