Adds a fail_if_exist option to index creation functions

[alexthomas93]

Description

Adds a fail_if_exist parameter to the create_vector_index and create_fulltext_index functions which causes them to fail when it is set to true and the index already exists. When set to false the functions do not fail if the index already exists.
