+++ This bug was initially created as a clone of Bug #1954747 +++

I am cloning this bug because: 
This BZ is to ensure that change made on 8.5.0 is propagated to 9.0.0.

Description of problem:
This bz covers multiple of bug fixes.

1. nbde_client - broken README.md due to the Automation Hub renderer.

    https://github.com/linux-system-roles/nbde_client/pull/46
    README.md - Adding a blank line after nbde_client_bindings -- merged

    VERIFICATION STEPS:
    Import the fixed nbde_client to AH and render the README.md.

2. SAP issue - lsr_role2collection.py does not convert the legacy role path 
   if the role is not the one to be converted.

    https://github.com/linux-system-roles/auto-maintenance/issues/65
    https://github.com/linux-system-roles/auto-maintenance/pull/68

    VERIFICATION STEPS:
    Convert sap-hana-preconfigure to the collection format using 
    lsr_role2collection.py having the pr/68 fix with the option
    --extra-mapping "timesync:redhat.rhel_system_roles.timesync,sap-base-settings:sap-base-settings,sap-preconfigure:sap-preconfigure"
    Check the converted README.md to have:
      - 'redhat.rhel_system_roles.timesync'
      - 'microsoft.rhel.sap-base-settings' (for RHEL 7.x until RHEL 7.5)
      - 'microsoft.rhel.sap-preconfigure' (for RHEL 7.6 and later and RHEL 8.x)
          - { role: microsoft.rhel.sap-base-settings }
          - { role: microsoft.rhel.sap-hana-preconfigure }
    Note: the namespace and the collection name of SAP might not be accurate.
    Before verifying this bug fix, please get the accurate names.
    

3. Collections - add requirements.txt, bindep.txt for requirements 
   [RHELPLAN-76440]

    https://github.com/linux-system-roles/auto-maintenance/pull/69
    Improve dependencies in the packaging #69

    https://src.fedoraproject.org/rpms/linux-system-roles/pull-request/7#
    #7 collections - add requirements.txt, bindep.txt for requirements

    VERIFICATION STEPS:
    Install rhel-system-roles rpm package and check this file exists.
    /usr/share/ansible/collections/ansible_collections/redhat/rhel_system_roles/requirements.txt
    and it contains these python dependencies:
    ==> /usr/share/ansible/collections/ansible_collections/redhat/rhel_system_roles/requirements.txt <==
    jmespath
    netaddr

A correction: the item 2 "SAP issue" should be separated as it does not belong to the "rhel-system-roles package".
