Injectable UI target data suppliers (#1123)

* initial proposal for injectible target data provider

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* improved selection of first entity in grid

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* introduced constructor to explicitely set DataCommunicator for a Grid

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* made data communicator for target grid injectable

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* adapted size page request to load only one entity for getting total elements, fixed grid duplicates in case lastModified property is the same for targets and rollouts

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* DeleteSupport rethrows the exception to be intercepted by error handlers

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* minor grid refactoring

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* adapted docu for base data providers

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* added custom filter data provider, made filter effectively immutable by cloning before data refresh

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* grid returns size directly from data provider instead of data communicator

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* restructured data provider/communicator dependency injection, added injectable data supplier for target filter view grid

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* do not remove confirmation dialog window from UI explicitely

Signed-off-by: Bogdan Bondar <Bogdan.Bondar@bosch.io>

* fixed sonar, added docs
