Update stryker init with new template for Stryker v4

[nicojs]

With Stryker v4 a number of things have changed that also need to be reflected in stryker init:

• No more test frameworks (simply remove that question).
• No more transpilers -> Replace with question about which Checker to enable.
• Add question about a build command to run.

Also some configuration options have been changed/added. These should be renamed in the template for the options. Also update initStrykerConfig in each package.json

Adding a nit: I recall that stryker init sets coverageAnalysis to all with command reporter, which results in an error message.
