[2.7.0] function tools error out with "bad request: unknown command: function-set:

[Dmitrii Shcherbakov]

juju exec --unit apache-httpd/0 'printenv JUJU_VERSION'
2.7.0

juju exec --unit apache-httpd/0 'type action-set'
action-set is /var/lib/juju/tools/unit-apache-httpd-0/action-set

juju exec --unit apache-httpd/0 'type function-set'
function-set is /var/lib/juju/tools/unit-apache-httpd-0/function-set

So the aliases are there, however running them results in errors:

juju exec --unit apache-httpd/0 'function-set -h'
ERROR bad request: unknown command: function-set

juju exec --unit apache-httpd/0 '/var/lib/juju/tools/unit-apache-httpd-0/function-set -h'
ERROR bad request: unknown command: function-set

juju exec --unit apache-httpd/0 'action-set -h'
Usage: action-set <key>=<value> [<key>=<value> ...]

Summary:
set action results
# ...

Just in case, the symlinks are there:

juju exec --unit apache-httpd/0 'stat `which function-set`'

Looks like this will be fixed in 2.7.1 based on testing of the 2.7.1 candidate build:

juju run --unit apache-httpd/0 'printenv JUJU_VERSION && function-set -h'
2.7.1
Usage: function-set <key>=<value> [<key>=<value> ...]

Yes, we fixed this just after 2.7.0 was released
