  - Split generic job by tests and reduce concurrency
    
    We have been performing some tests using the Ubuntu Jammy image.
    While doing such tests, we realized that the newest image would
    need more RAM to be spawned successfuly, and that brings the need
    to bump the memory for such VMs. While testing with the memory
    bump, we realized that the generic driver would face issues with
    such change.
    
    We have seen a couple of tests failing due to the share manager
    service loosing connection to the database, and this is usually
    caused when we have a lack or high consumiption of resources in
    a VM. Reducing the concurrency itself should work, and then
    we would have the jobs passing. However, in reducing the
    concurrency, this job will take longer to run, considering it
    will only use one of the available threads, and it can lead to
    this job's possibility to hit the 3 hours pre-scheduled limit.
    
    To avoid that, we decided to:
    
    Have this change to reduce the concurrency of the manila generic
    driver job to 1, so we can avoid these failures, as well as
    split the generic driver job into two jobs:
    
    - manila-tempest-plugin-generic
    - manila-tempest-plugin-generic-scenario
    
    The generic one will take care of the API testing as we currently
    know and have been doing. The scenario one will run all of the
    scenario tests.
