Reorganize templates

[jpkrohling]

The current organization of the templates has become confusing (production vs. production-elasticsearch, for instance).

A recommendation is the following:

.
├── development (currently, it's the all-in-one)
│   └── development.yaml
└── production
    ├── cassandra.yaml
    ├── elasticsearch.yaml
    └── jaeger.yaml

Of course, the tests have to be adjusted for this.

@pavolloffay what do you think?

Proposed structure looks good. The names should contain jaeger prefix eg. jaeger-production.yml.

Currently, It's also odd that we add -template suffix. It should be removed.

This might be tricky task, it requires some arquillian skills to use different arquillian.xml in the same maven module. This will also affect travis build as we are using travis stages per storage.
