Class for parsing the output of `yum -C --noplugins repolist` command.
Typical output of the command is::
repo id repo name status

!rhel-ha-for-rhel-7-server-e4s-rpms/x86_64 Red Hat Enterprise Linux High Availability (for RHEL 7 Server) Update Services for SAP Solutions (RPMs) 272

Attributes:
data (list): list of repos wrapped in dictionaries
repos (dict): dict of all listed repos where the key is the full repo-id without "!" or "*".
But you can get it from the value part if needed. For example::
self.repos = {
'rhel-7-server-e4s-rpms/x86_64': {
'id': 'rhel-7-server-e4s-rpms/x86_64',
'name': 'Red Hat Enterprise Linux 7 Server - Update Services for SAP Solutions (RPMs)',
'status': '12,250'
},
'rhel-ha-for-rhel-7-server-e4s-rpms/x86_64': {
'id': '!rhel-ha-for-rhel-7-server-e4s-rpms/x86_64',
'name': 'Red Hat Enterprise Linux High Availability (for RHEL 7 Server) Update Services for SAP Solutions (RPMs)',
'status': '272'
},
'rhel-sap-hana-for-rhel-7-server-e4s-rpms/x86_64': {
'id': '*rhel-sap-hana-for-rhel-7-server-e4s-rpms/x86_64',
'name': 'RHEL for SAP HANA (for RHEL 7 Server) Update Services for SAP Solutions (RPMs)',
'status': '21'
}
}
rhel_repos(list): list of all the rhel repos and the item is just the repo id without server and arch info. For example::
self.rhel_repos = ['rhel-7-server-e4s-rpms', 'rhel-ha-for-rhel-7-server-e4s-rpms', 'rhel-sap-hana-for-rhel-7-server-e4s-rpms']
