Generate issues command

[pedropb]

Hi again!

I finally took some time to finish this implementation.

I created a new command called generate-issues that takes 2 parameters, <project> and <model>. The main objective of this command is to generate a set of issues from a predefined JSON model.

A common use case is:

• Suppose there is a task #37, subject: "Implement some feature"
• For this task we have a known set of subtasks like:
  • Define interfaces
  • Write unit tests
  • Write code to pass unit tests
  • Refactor code

We would then define a model called TDD.json like this:

{
    "globals": {
        "assignee": 1,
        "tracker": "Task"
    },
    "issues": [
        {"subject": "Define interfaces"},
        {"subject": "Write unit tests"},
        {"subject": "Write code to pass unit tests"},
        {"subject": "Refactor code"}
    ]
}

Then we would import the model into RedmineCLI: redmine import-model <path_to_TDD.json> TDD.

Finally we would generate the subtasks for the assigned parent issue: redmine generate-issues <project> TDD --parent 37.

Aside from generate-issues and import-model, there are also list-models and remove-model commands to provide all possible use-cases regarding model management.

I hope you like this new feature. It's proven to be very useful for me.
