MDL-59204 analytics: changed get_name so that it returns a lang_string

This was done for indicators, targets and time splitting methods so that we
can get the string identifier and component in order to display a help_icon.

The functions were also made abstract, removing the default implementation.
Indicators, targets and time splitting methods should define this function.
