os-apply-config --key doesn't work for non-string values

[Roman Podoliaka]

When trying to print a non-string value I get the following error:

$ sudo os-apply-config --key nova.baremetal.use_file_injection --type raw
Traceback (most recent call last):
  File "/usr/local/bin/os-apply-config", line 10, in <module>
    sys.exit(main())
  File "/opt/stack/venvs/os-apply-config/local/lib/python2.7/site-packages/os_apply_config/apply_config.py", line 235, in main
    opts.fallback_metadata)
  File "/opt/stack/venvs/os-apply-config/local/lib/python2.7/site-packages/os_apply_config/apply_config.py", line 68, in print_key
    value_types.ensure_type(config, type_name)
  File "/opt/stack/venvs/os-apply-config/local/lib/python2.7/site-packages/os_apply_config/value_types.py", line 37, in ensure_type
    if not re.match(TYPES[type_name], string_value):
  File "/opt/stack/venvs/os-apply-config/lib/python2.7/re.py", line 137, in match
    return _compile(pattern, flags).match(string)
TypeError: expected string or buffer

This is caused by the fact, that ensure_type() function accepts string values, but a parsed is passed (in this case, bool).

    Fix printing of keys with non-string values

    When trying to print a key which has a non-string value
    (e.g. bool or int), TypeError exception is raised. This
    is caused by the fact, that ensure_type() function accepts
    string values, but parsed values are passed (i.e. False
    instead of 'False' or 12 instead of '12' and so on).
