dunner do install commands to quick install tools globally

[agentmilindu]

Is your feature request related to a problem? Please describe.
We sometimes need a way to quickly install tools which we don't need in the long run. For example, when you get a project that needs Maven 3 to work, and if you know you are not going to use it after the current project, why install it on your machine permanently and why go through all the hassle in installing tools like this?.

Describe the solution you'd like
I should be able to quickly install tools with Dunner like below

dunner install <tool-docker-name>#
#eg:-
dunner install mvn

This should install Maven 3 Docker and bind to our bin path. Then when we run mvn it should be the Docker images that runs the given command.s

Describe alternatives you've considered
There are a few tools that do only this. But we can give this feature in Dunner as a convenience feature.
