Allocator module - Modify the directory name for machines deployed in AWS

[c-bordon]

It is necessary to modify the name of the directory that is created with the machine information for the AWS provider, the name of the directory should be:

• If we use the --instance-name parameter, the directory must have that name
• If we use the --label-issue parameter, the same instance name should be used for the directory name
• If none of these parameters are used, the directory should be the instance id as it is now.

We will have to add a unique identifier as in the case of Vagrant, to avoid coincidences in the directories.
