Dependencies update

[scottinet]

Description

• Now uses Kuzzle common objects v3.0.6
• Elasticsearch client now refuses the 5.x API version => changed to 5.4
• Fix new errors detected by eslint v4 (mainly indentation and multiple spaces lint errors)
• Cucumber has NOT been upgraded: the current version is 3.0.0 but it is currently broken and unusable in our project

Other changes

Some commands of the CLI were broken due to recent changes to the getEventName method of the funnel controller. This is now fixed.
