Adds a new function in the workbench file called "update_files", adds an integration test in islandora_tests.py and slightly modifies functions in workbench_utils.py to include "update_files" as a task.

How to test / verify this PR?

For the integration test, open islandora_workbench folder in terminal, then run "python3 tests/islandora_tests.py TestUpdateFileName". To test the usage of the task, you have to create a config file with task as "update_files" and host, username, password, input_csv. For the csv file, you only need the file_id (the file you are trying to update) and filename (the new, updated file name).
