Title: Add elasticsearch as annotations source

Experimental support for elasticsearch as annotation source.
Current feature:
- allow to search against any index ("toto", "_all", "toto,titi")
- allow any query

Limitations:
- static fields used for timestamp and annotation message
- size of request is hard-coded
- direct use of $http instead of elasticsearch ejs client
- no tests

Fix #201
