[FEATURE] Support `condition` in `import` blocks

[ottramst]

Describe the solution you'd like

Would like to see conditional imports. Example:

import {
  condition = global.environment == "staging"
  source = "/environments/staging/config.tm.hcl"
}

This could be leveraged to pull in specific globals based on some metadata etc.

Hi @ottramst,

Thanks for reaching out with new ideas :rocket:

This feature is already on our backlog. We are working on other features at the moment, like vendoring support and improved ternary support, but as soon as we have conditional importing we will let you know :smiley:
