Configure enclosure escape character

#!/bin/bash

#
# This script uses the Masking Engine APIs to configure the enclosure escape character feature.
# The script uses the /login API to obtain an authentication token and then uses the PUT /file-metadata API.
#
# To use this script, you must set DOUBLE_ENCLOSURE, CUSTOM_ENCLOSURE_ESCAPE_CHARACTER, ESCAPE_ENCLOSURE_ESCAPE_CHARACTER and RULESET_ID accordingly
