Add option to specify package version for zopen-install

Feature Title

Add option to specify package version for zopen-install

Feature Description & Current Pain Points

Currently there's the −−select option which displays the available versions for a package and allows to select one for installation. Seems like there's no option to specify the version that I want installed on the command line.
Let's say I have "nats" installed on multiple systems. If there's an issue with the latest package, and I want to revert back to a previous version, seems like the only option is to do it manually on all the systems. If I could specify the version on the command line, I could run the command using ansible on all the systems I'd like to change.

Proposed Solution & Expected Behavior

zopen-install command should allow specifying the package with a version to install. So for
zopen-install nats:STABLE_NATSport_3825 will install the version STABLE_NATSport_3825 of the nats package.
If a more recent package is already installed, warn the user and prompt to apply. --force or --yes should continue with the installation without prompting the user.

Environment Details (Optional)

zopen version 0.8.4

We need to document this but you can use zopen install nats%STABLE_NATSport_382 to accomplish this. You can also add a .pinned file in the nats install directory to pin it so that it doesnt get upgraded. We probably should add a command/option for this. @DevonianTeuchter ?

Thanks @IgorTodorovskiIBM, that worked for me.
