* Base Report data store utility functions - 1
Standardizing the data store classes will be easier if the base class contains simple utility functions
that can replace logic implemented in multiple data stores.
- set_db_table_name() assigns a WP DB table name class variable for the data store
- get_db_table_name() retrieves the WP DB table name
- prepend_table_name() prepends a field in a query fragment with the data store table name
* add context, clause handling, and filters to reports data store
* add generated SQL clauses to class properties
* reduce id getter logic to single function with filter, add phpdocs to new filters
* update table_name to private string for use in constructor
* extract SQL query clause handling to its own class
- Will allow for use in subquery processing without creating a get_data stub
- Swap parameter order in add_sql_clause for readability
- Add support for clearing multple clauses in one call

* refactor taxes and tax stats data stores
* refactor variations data store
* refactor product and product stats data stores

* refactor order and order stats datastores
- use consistent visibility on initialize_queries()
- update db_table_name logic to use static keyword instead of self
* fix missed whitespace
* fix segmenting query, add SqlQuery join clause
* DRY data store constructors, class properties
