Allow arrays parameters

[ogizanagi]

This allow to have array parameters. For instance:

#fixtures.yml
parameters:
    usernames: ['Alice', 'Bob', 'Ryan']

Nelmio\Entity\User:
    user{1..50}:
        username: <randomElement(<{usernames}>)>

and associative arrays:

parameters: 
    config: { host: localhost, port: 4567 }

Without this change, you'll get an Array to string conversion error:

However, note that it is already doable by enforcing the yaml array to be interpreted as a string:

parameters:
    usernames: "['Alice', 'Bob', 'Ryan']"

Could you add a test for it?

[ogizanagi]

Tests added. One or the other should be sufficient, though.
Let me now if I should remove one.

Thanks looks good to me, hopefully I am not missing anything

@Perfect-Web it works fine on 3.x I didn't check on 2.x. If it doesn't and you wish it to work, feel free to open a new issue for it or a PR, but don't dig zombies please :)
