Support sf 3.0

[Nyholm]

It could be fun to try to support Symfony 3.0. Is this possible for the next major version?

Is this bundle actually using outdated features to support sf3?

[Nyholm]

I dont know. Part of resolving this issue is to investigate that and test run it with symfony 3

Sure, let's give it a try

For one, the services.yml config needs to be updated. The syntax to reference a service by name has changed to be valid YAML.

# Before
services:
    dizda.cloudbackup.manager.database:
        class: Dizda\CloudBackupBundle\Manager\DatabaseManager
        arguments:
          - @logger

# After, notice the last line
services:
    dizda.cloudbackup.manager.database:
        class: Dizda\CloudBackupBundle\Manager\DatabaseManager
        arguments:
          - '@logger'
