Print NetBox version when running upgrade.sh

[markkuleinio]

NetBox version

v3.7-beta1

Feature type

New functionality

Proposed functionality

When running upgrade.sh it would be beneficial to see what is the actual NetBox version that is being prepared.

Something like

echo "NetBox version is $(grep ^VERSION netbox/netbox/settings.py | cut -d\' -f2)"
NetBox version is 3.7-beta1

would maybe be enough somewhere in the beginning of upgrade.sh.

Use case

Sometimes there is confusion when symlinking or pulling the versions here and there and running upgrade.sh, what is the actual codebase that is being activated.

Database changes

None

External dependencies

None

I would add, it might be wise too break until there is input after that (unless running non-interactively).

I can submit the PR. I can add the pause in interactive mode (let's discuss in the PR if something needs adjusting).
