Dependecy update

[mervit]

I need to use package symfony/translation in version 3.4.
That means i need package symfony/validator at least in version 4.0.x (https://packagist.org/packages/symfony/validator#4.0.x-dev)

The highest version of your project need symfony/validator 2.7.*

Please create new version with updated dependencies.

I cant use your project any more till dependency problem will be solved.

Thank you

This same constraint issue also means the SDK won't work on Symfony 4 applications.
