Update and clean up HK and Local Pool Modules

 ## Changed
 
+- Complete overhaul of HK subsystem. Replaced local data pool manager by periodic HK
+  helper. The shared pool and the periodic HK generation are now distinct concepts.
+- The local HK manager was replaced by a periodic HK helper which has reduced responsibilities.
+  It takes care of tracking the HK generation using a set specification provided by the user.n
+  However, it leaves serialization of the HK data completely to the developer. This removes a major
+  constraint on the format of the HK data, which was previously constrained to implementors of a
+  certain base class.
+- The former set classes and pool objects are still available for HK set specification and
+  generation. The API has changed, but the general usage and their architecture has not.
+- A new set of set classes and helper objects to specify HK sets and data which does not need to be
+  shared was added as well. The majority of datasets do not need to be shared anyway.
+- The non-shared API retain the capability of appending of a validity blob for each piece of set
+  data at the end of the HK data. For both non-shared and shared data, this capability can be
+  specified in the constructor, and defaults to true.
 - Improved File System Abstraction to be more in line with normal filesystems.
 - CFDP implementation was improved, has now even less dependencies on other FSFW components
   and allows one inserted packet per state machine call.

-/**
- * @brief 		This interface is implemented by classes which posses a local data pool (not
- * the managing class). It defines the relationship between the local data pool owner and the
- * LocalDataPoolManager.
- * @details
- * Any class implementing this interface shall also have a LocalDataPoolManager member class which
- * contains the actual pool data structure and exposes the public interface for it.
- *
- * The local data pool can be accessed using helper classes by using the
- * LocalPoolVariable, LocalPoolVector or LocalDataSet classes. Every local pool variable can
- * be uniquely identified by a global pool ID (gp_id_t) and every dataset tied
- * to a pool manager can be uniqely identified by a global structure ID (sid_t).
- *
- * All software objects which want to use the local pool of another object shall also use this
- * interface, for example to get a handle to the subscription interface. The interface
- * can be retrieved using the object manager, provided the target object is a SystemObject.
- * For example, the following line of code can be used to retrieve the interface
- *
- *    HasLocalDataPoolIF* poolIF = ObjectManager::instance()->
- *             get<HasLocalDataPoolIF>(objects::SOME_OBJECT);
- *    if(poolIF != nullptr) {
- *        doSomething()
- *    }

- * @brief 		This class is the managing instance for the local data pool.
- * @details
- * The actual data pool structure is a member of this class. Any class which
- * has a local data pool shall have this manager class as a member and implement
- * the HasLocalDataPoolIF.
- *
- * The manager offers some adaption points and functions which can be used
- * by the owning class to simplify data handling significantly.
- *
- * Please ensure that both initialize and initializeAfterTaskCreation are
- * called at some point by the owning class in the respective functions of the
- * same name!
- *
- * Users of the data pool use the helper classes LocalDataSet,
- * LocalPoolVariable and LocalPoolVector to access pool entries in
- * a thread-safe and efficient way.
- *
- * The local data pools employ a blackboard logic: Only the most recent
- * value is stored. The helper classes offer a read() and commit() interface
- * through the PoolVariableIF which is used to read and update values.
- * Each pool entry has a valid state too.
- * @author 		R. Mueller

+ * LocalDataPoolManager.
+ * @details
+ * Any class implementing this interface shall also have a LocalDataPoolManager member class which
+ * contains the actual pool data structure and exposes the public interface for it.
+ *
+ * The local data pool can be accessed using helper classes by using the
+ * LocalPoolVariable, LocalPoolVector or LocalDataSet classes. Every local pool variable can
+ * be uniquely identified by a global pool ID (gp_id_t) and every dataset tied
+ * to a pool manager can be uniqely identified by a global structure ID (sid_t).
+ *
+ * All software objects which want to use the local pool of another object shall also use this
+ * interface, for example to get a handle to the subscription interface. The interface
+ * can be retrieved using the object manager, provided the target object is a SystemObject.
+ * For example, the following line of code can be used to retrieve the interface
+ *
+ *    HasLocalDataPoolIF* poolIF = ObjectManager::instance()->

+ *
+ * The manager offers some adaption points and functions which can be used

+ *
+ * Please ensure that both initialize and initializeAfterTaskCreation are
+ * called at some point by the owning class in the respective functions of the

+ *
+ * Users of the data pool use the helper classes LocalDataSet,
+ * LocalPoolVariable and LocalPoolVector to access pool entries in
+ * a thread-safe and efficient way.
+ *
+ * The local data pools employ a blackboard logic: Only the most recent
+ * value is stored. The helper classes offer a read() and commit() interface
+ * through the PoolVariableIF which is used to read and update values.
+ * Each pool entry has a valid state too.
