Kibana plugins installation fix

[Infra-Red]

Hi , I create fix for kibana plugins installation. If you try to add plugins to deployment manifest current logsearch release will return nil value for plugin location:

undefined method `start_with?' for nil:NilClass

This behavior can be described with next example, here shows the correct and incorrect behaviour:

2.2.4 :001 > a,b = [1,2]
 => [1, 2]
2.2.4 :002 > a
 => 1
2.2.4 :003 > b
 => 2
2.2.4 :004 > a,b = [1,2].first
 => 1
2.2.4 :005 > a
 => 1
2.2.4 :006 > b
 => nil
2.2.4 :007 >

I also added the fix for kibana environment variables. Next issue occurred during preparing of deployment :

Error 100: Error filling in template `kibana_ctl' for `kibana/0' (line 22: undefined method `keys' for ["CF_API_URL", "https://api.example.com"]:Array)

@Infra-Red: I'm terribly sorry, I forgot about this PR a bit.

What are you trying to fix exactly? We are using this release without issues with kibana plugins and env settings. Could you show me your kibana properties from your deployment manifest?
