fccc728fcc MDL-64783 analytics: Performance improvements 
- Removed redundant query to analytics_predict_samples
- Analysers API now uses recordsets to iterate through the analysable
  elements. They take the last analysed time into account.
- New method for targets so there is no need to always update the last
  analysis time. Useful for lightweight targets.

9f690999ec MDL-64783 analytics: Performance improvements and internal refactoring 
The base classes analyser and time-splitting method had too many
reponsibilities. A new analysis class has been created.

aa8af6fcfc MDL-61667 analytics: Fix checking that a given model does not exist 
The original implementation did not work well for checking that the
given model does NOT exist. If no record was found in the
analytics_models table, the code execution continued and it reached the
moment when indicators were checked. If no indicators were provided, the
call ended up with error 'array_keys() expects parameter 1 to be array,
boolean given' (because indicators were set to false).

3b7c7918f3 MDL-61667 analytics: Deprecate the add_builtin_models() method 
The functionality of the \core_analytics\manager::add_builtin_models()
method is to be replaced with automatic update of models provided by the
core moodle component. There is no need to call this method explicitly
any more. Instead, adding new models will be done by updating the
lib/db/analytics.php file and bumping the core version.

c679d39c36 MDL-64996 analytics: Don't mark static model as untrained after clearing 
Static predictions models (i.e. those using a target based on
assumptions, not facts) are always considered as trained. Clearing them
must not mark them as untrained. Doing so would make them being skipped
by the prediction scheduled task.
