Update Zend Coding Standard to v2

[tux-rampage]

There are a lot of new conventions that are not covered by the current phpcs ruleset of zend-coding-standard (v1.x).

Some examples are (incomplete list):

• Whitespace after cast operators
• Whitespace after not operator (!)
• Whitespaces before and after ternary operators
• Trailing comma for the last element in array declarations

A new coding style and tooling is currently work in progress at zendframework/zend-coding-standard#5. When this PR is merged and v2 is released this zend-di should integrate it.

Depending on my availability, I'll perform the tests as suggested in the mentioned PR.
