Lava init commands.
When invoking:
`lava init [DIR]`
the command will create a default directory and files structure as follows:
DIR/
|
+- JOB_FILE.json
+- tests/
|
+ mytest.sh
+ lavatest.yaml
If DIR is not passed, it will use the current working directory.
JOB_FILE is a file name that will be asked to the user, along with
other necessary information to define the tests.
If the user manually updates either the lavatest.yaml or mytest.sh file, it is
necessary to run the following command in order to update the job definition:
`lava update [JOB|DIR]`
