Replace INFO blocks in the documentation with valid styles

Description

You can see here that the "INFO" admonition doesn't exist in the Asciidoc syntax: http://asciidoctor.org/docs/user-manual/#style

And indeed, during the build we get this kind of messages:

1 asciidoctor: WARNING: elasticsearch-integration.asciidoc: line 444: invalid style for example block: INFO
