NetBox dropped "clearcache" management command

[sleinen]

Netbox PR #14461 removed the clearcache management command, as proposed in issue #14458. This change is included in NetBox v3.7.0. The Ansible role tries to call it for NetBox v3.2.3+, which leads to errors when using it to install/upgrade to 3.7.x:

TASK [lae.netbox : Clear cached data in NetBox] *************************************************************************************************
skipping: [netbox-dev.switch.ch]

TASK [lae.netbox : Clear cached data in NetBox 3.2.3+] ******************************************************************************************
fatal: [netbox-dev.switch.ch]: FAILED! => {"changed": false, "cmd": ["./manage.py", "clearcache"], "msg": "stdout: Unknown command: 'clearcache'. Did you mean clearsocial?\nType 'manage.py help' for usage.\n\n:stderr: Unknown django command: clearcache"}

We should skip that step for newer versions of NetBox.

Fixed per #166 I believe?

Oops, absolutely! Sorry, I should have checked beforehand.
