Heart: Remove the mechanism which removes logging-data from Heart DB by explict data-query

In Tizen 3.0 and Early Tizen 4.0, we observed whether there are some requirements for deleting logging-data explictly.

Meanwhile, the logging functions like logging_get_latest_in_cache,logging_read_foreach has been used for several purposes.
However, there are some bugs that the logging functions do not consider such deleting data cache entries in module cache.
Thus, our plan was to improve the functions if there are some requirement for deleting logging-data explictly.

However, there are no requirements about it.
Thus, finally, we decided to remove the explict logging-data removing mechanism because there are no use cases.

Thus, from now, data of heart DBs will be removed according to just impliict(internal) rule.
That is, in this time, the old data is removed automatically when the DB size limit is reached.
