v.0.1.0

• We can now refresh cached decisions in stream mode.
• We use monolog and log specific events by level.
• We made the watcher client more flexible, adding more methods to get a better control of the CrowdSec context.
• We removed the useless "composer" container to keep only "php", as composer is included inside the "php" container.
• We now use the string version of IP as the cache keys can not be integers.
• We test more cases (remove decisions, add some new, refresh caches and check the cache states)
