Generate input file for each test

[marioaag]

Following the idea of generate an input file that contain the recipe (configuration and parameters) to be able to replay the test execution.

This issue is to implement the generation of those files as part of individual test results directories.

An idea of what is the expectation could be generated with avocado list --resolver --write-recipes-to-directory=/your/dir -- your-tests

And the ultimate goal is that those files could be executed with avocado-runner-$type runnable-run-recipe
