Use Ruby >= 1.9 syntax for hashes. Prefer { a: :b } over { :a => :b } (#1253)

Use Ruby >= 1.9 syntax for hashes

* Required Ruby version is >= 2.2, so It's better to use prefer `{ a: :b }` over `{ :a => :b }` in hash syntax.
* It's hard to modify manufally all points, so I've installed rubocop and enabled only `Style/HashSyntax` (All cops are disabled by default)
* Executed `rubocop --auto-correct`
