util: read_cc_from_cmdline handle urlencoded yaml content (#275)
Add support for additional escaping of formatting characters
in the YAML content between the 'cc:' and 'end_cc' tokens. On
s390x legacy terminals the use of square brackets [] are not
available limiting the ability to indicate lists of values in
yaml content. Using #5B and #5D, [ and ] respectively enables
s390x users to pass list yaml content into cloud-init via
command line interface.
