fix glooctl install: Replace deprecated distutils

[puertomontt]

Description

distutils package used in glooctl install script is deprecated. Currently trying to install will give an error:

curl -sL https://run.solo.io/gloo/install | sh
Using /opt/homebrew/bin/python3
Traceback (most recent call last):
  File "<string>", line 1, in <module>
    import sys; from distutils.version import StrictVersion, LooseVersion; from json import loads as l; releases = l(sys.stdin.read()); releases = [release['tag_name'] for release in releases];  filtered_releases = list(filter(lambda release_string: len(release_string) > 0 and StrictVersion.version_re.match(release_string[1:]) != None and StrictVersion(release_string[1:]) < StrictVersion('2.0.0') , releases)); filtered_releases.sort(key=LooseVersion, reverse=True); print('\n'.join(filtered_releases))
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'distutils'

The replacement package recommended by Python is not installed by default. So we decided to drop the dependency on python and use jq instead.
