In order to not add a new configuration key that is needed by
all the kafka stream use case applications extract the configuration
keys to the kafkastreams common project.

To allow using the schema registry kafka streams builder
takes an URL for using late the avor schema regitstry
factory.

The Project is renamed to theodolite and therefore all packages
should be renamed likewise.

This allows the usecases to create its own Properties object if
needed.

Create an abstract KafkaStreamsBuilder class that can be used in kafka
streams use cases.
This should reduce the redundancy for reconfigure the properties in
every streams application.
Now only the topology needs to be defined by the use cases.

- Added application-kafkastreams-common project
- modified root gradle project
- configure eclipse quality tools and formatting
