CCDE-295: Allow CREATE TEMP TABLE query to be ran from a SQL file

[isichei]

At the moment pydbtools has a create_temp_table method. It would be useful to allow users to do this via an SQL file.

CREATE TEMPORARY TABLE <table name> AS (
  <normal SQL query>
)

Would then trigger:

pydb.create_temp_table(sql="<normal SQL query>", table_name = "<table name>")
