[utils] Fix error when creating labels

The GrimoireUtils creation of labels does now have the same behaviour
as the general GrimoireLib's for dates. The initial date in the analysis
should be greater or equal to the proposed initial date and the last date
of the analysis should be strictly less than the last date proposed

Thus, a day is subsctracted from the last proposed date of analysis.

General API fixing: https://www.bitergia.net/redmine/issues/4045

- get_trends_all_items: Moved to _get_trends_all_items. It should not be called outside metrics class.
- get_items_out_filter_sql: Moved to a private function where it is used (just one place). In a future refactoring probably we should remove it.
- get_bots_filter_sql: Moved to DSQuery class. Probably we should review it, but it is a helper class for building SQL addhoc and filtering bots.
[metric] Add some documentation to root metrics class
