Collapse apex-pdp maven model submodules

This review collapses all the code in six podel submodules into a single
model module. There are no code changes, just files moved around.

This change reduces the complexity of the code structure and speeds up
the build.

-/**
- * This class is used to define an album of context.
- *
- * <p>A context album is a distributed map of context that will be distributed across all process instances that require
- * access to it. This class defines the schema (structure) of the items in the context album, whether the items on the
- * context album are writable or not, and what the scope of the context album is.
- *
- * <p>The structure of items (objects) the context album is defined as a schema, which is understood by whatever schema
- * implementation is being used for the context album.
- *
- * <p>The scope of a context album is a string field, understood by whatever distribution mechanism is being used for
- * the context album. The distribution mechanism uses the scope of the context album to decide to which executable
- * entities a given context album is distributed.
- *
- * <p>The writable flag on a context album defines whether users of a context album can write to the context album or
- * just read objects from the context album.
- *
- * <p>Validation checks that the album key and the context schema key are not null and that the scope field is not
- * undefined and matches the regular expression SCOPE_REGEXP.

-/**
- * This class holds a data schema definition in Apex. A data schema describes the structure of a single atom of data
- * handled by Apex. This atom of data can be a primitive type such as an integer or a string, or it can be a more
- * complex data type such as a Java object or an object described using a data definition language such as Avro. The
- * schema flavour defines the type of schema being defined and the schema itself defines the schema. The schema flavour
- * is used by Apex to look up and load a plugin class that understands and interprets the schema definition and can
- * create instances of classes for the schema.
- *
- * <p>An {@link AxContextSchema} is used to define each parameter in Apex events, the messages that enter, exit, and are
- * passed internally in Apex. In addition, an Apex {@link AxContextAlbum} instances hold a map of
- * {@link AxContextSchema} instances to represent the context being managed as an {@link AxContextAlbum}. For example,
- * the state of all cells in a mobile network might be represented as an {@link AxContextAlbum} with its
- * {@link AxContextSchema} being defined as @code cell} objects.
- *
- * <p>Validation checks that the schema key is not null. It also checks that the schema flavour is defined and matches
- * the regular expression SCHEMA_FLAVOUR_REGEXP. Finally, validation checks that the defined schema is not a blank or
- * empty string.
