Adding context flag on server install

[danielbdias]

This PR adds a context flag to allow users to bypass the inputs on our CLI.

With that, we can install tracetest on Kubernetes by running the following command:

tracetest server install --run-environment kubernetes --mode with-demo --kubernetes-context docker-desktop

Changes

• Added kubernetes-context flag on server install command

Checklist

Do we expect this to be part of this release? if so, we'll have to test this A LOT

It could be good to have it on the same release as this PR (#2462). What type of tests of you see us doing @xoscar ?

At first glance, I believe that we can expand our Testing guidelines to include installation tests with and without these params.

If needed I can anticipate and at least add some tests in our CI for the docker-compose installer.
