Simplify test configuration.
Split tests into unit test and integration test run.

This properly fixes the test setup, taking into account that @ActiveProfile by default replaces any profiles set via environment variable or system property.
It turns out that the hasNext calculation in RowDocumentIterator was wrong because
a) isBeforeFirst and isBeforeLast return both false when the ResultSet is empty.
b) isBeforeFirst and isBeforeLast aren't necessarily implemented for all ResultSets and for example DB2s ResultSet implementation don't support it by default.
Closes#1615
Add sophisticated converter to read aggregates from a RowDocument including support for maps, collections, subdocuments, and embeddables considering registered converters.
Use ResultSetRowDocumentExtractor to extract result multi-sets into RowDocument and then later apply object mapping.

The construction of the DataAccessStrategy happened before the MappingContext was properly setup.
This is now fixed.
A test utilizes Single Query Loading, if it activates the profile singleQueryLoading
Closes#1606
Push JDBC-specific simple types into JdbcPostgresDialect instead of having these in the top-level dialect that shouldn't be tied to any driver technology.
Introduce profile to run Postgres tests only.
Transform the tabular structure into a graph of RowDocument associated with nested documents and lists.
Add container license acceptance for updated container images.

Single Query Loading loads as the name suggests complete aggregates using a single select.
While the ultimate goal is to support this for all aggregates, this commit enables it only for simple aggregate and also only for some operations.
A simple aggregate is an aggregate that only reference up to one other entity and does not have embedded entities.
The supported operations are those available via `CrudRepository`: `findAll`, `findById`, and `findAllByIds`.
Single Query Loading does NOT work with the supported in memory databases H2 and HSQLDB, since these do not properly support windowing functions, which are essential for Single Query Loading.
To turn on Single Query Loading call `RelationalMappingContext.setSingleQueryLoadingEnabled(true)`.

AggregatePath replaces PersistentPropertyPathExtension.
It gets created and cached by the RelationalMappingContext, which should be more efficient and certainly looks nicer.
