Feat | Redis Translation storage

[Guikingone]

Feature: Every translation should be stored inside Redis.

Specification:

• A RedisConnector should be created, it should use the TagAwareAdapter class from symfony/cache and the Predis client.
• A RedisTranslationWriter should be created in order to access the redis instance and save an array of RedisTranslation which contain every translation key/value.
• A RedisTranslationRepository should be created in order to retrieve a RedisTranslation stored into the Redis instance.
• A RedisTranslationWarmer should be created, this one's gonna use the CloudTranslationWarmer in order to translate and store the content in the Redis instance.

Constraints:

• Every translation must declare: channel, tag (UUID), key, value and _locale.
• The RedisTranslationRepository should allow to retrieve a translation using the filename (of the translation) or via the _locale and the filename.

Tests:

Performances:

• The memory peak (RedisTranslationRepository->getSingleEntry()) should be under 100kb.
• The memory peak is under 80kb for the RedisTranslationWriter->write() process.
• The network in call should be under 50b.
