62e1b79cb0 MDL-65067 analytics: Strengthen format_weeks detection
The public function get_section_dates($section, $startdate = false) is
only defined in format_weeks, not in format_base.

As other formats can (and format_topcoll has) declare a different
get_section_dates public method, merely checking that it exists is not
sufficient to guarantee that it can be called with just a section object.

Check that the format either is, or is a subclass of format_weeks.

f07d93de9d MDL-59030 analytics: Social breadth accepting more than level 2
Even if core indicators are limited to level 2 we should not block
other activities from implementing up to level 5.

5c5cb3ee15 MDL-59265 analytics: Rename machine learning backend method
- Method names renamed to avoid interface changes once
  we support regression and unsupervised learning
- Adding regressor interface even if not implemente
- predictor interface comments expanded
- Differentiate model's required accuracy from predictions quality
- Add missing get_callback_boundary call
- Updated datasets' metadata to allow 3rd parties to code
  regressors themselves
- Add missing option to exception message
- Include target data into the dataset regardless of being a prediction
  dataset or a training dataset
- Explicit in_array and array_search non-strict calls
- Overwrite discrete should_be_displayed implementation with the binary one
- Overwrite no_teacher get_display_value as it would otherwise look
  wrong
- Other minor fixes

0690a271c3 MDL-59067 analytics: Store indicator calculations
This was supposed to be split into multiple commits to make it easier to understand
but I failed to do it properly. So this is the list of changes:

- New analytics_indicator_calc db table to store indicators calculations
- Reuse previous calculations during prediction/training; other models
  previous calculations should also be reused as long as they belong to
  the same sample (sampleid depends on sampleorigin), time range and indicator
- Allow bulk inserting of these calculations as this can hurt database performance
- Block the same analysable to be analysed for training and for prediction
- Use a new instance of the target and use it for is_valid_* functions
  as using ::is_valid_sample can lead to problems if people
  uses it to cache stuff
