sqlite: SQLite rust migrations

retry: This macro wraps a function with retry calls to keep calling the function until the error “database is locked” is not raised anymore.

ToVoid: This trait provides some syntax to shorten queries execution returning ()

create_temp_db_file: Create a temporary database file that won’t be cleaned-up automatically
skip_if_postgres: This function can be used to avoid running a test if the postgres database is used.
with_application_dbs: This function can be used to run some test code with the 3 different databases implementations of the application database
with_dbs: This function can be used to run some test code with the 3 different databases implementations
with_postgres: This function can be used to run some test code with a postgres database
with_sqlite_dbs: This function can be used to run some test code with the 2 SQLite databases implementations
