The CLI error messages for users with reader role were not clear to the
operator and this change fixes this.
The problem was caused by an exception in string manipulation that was
handled locally (the position "2" of the list of lines didn't exist,
check file "base.py").
The error messages of DC CLI commands have either the format
"<Explanation of why the operation failed>
ERROR (app) Unable to <do operation X on subcloud Y>"
or simply "ERROR (app) <Explanation of why the operation failed>".
In the case of command "dcmanager subcloud reconfig", that uses the
first format, the part where "<Explanation of why the operation failed>"
was printed was missing, so a "print(exception)" was added (see
"subcloud_manager.py" file, some other declarations of method
"_get_resources" in the same file use this pattern).
Test Plan:
PASS: In a DC with this change present, create a new openstack user with
reader role and through this user execute the commands:
dcmanager subcloud list
dcmanager subcloud manage subcloud1
dcmanager subcloud-group add --name test
dcmanager subcloud reconfig --deploy-config file001 subcloud1
and check that the "subcloud list" command is executed without errors
and that the error message of the other commands changes from
"b'<html>\n <head>\n <title>403 Forbidden</title>\n </head>\n <body>\n
<h1>403 Forbidden</h1>\n Access was denied to this resource.<br /><br
/>\n\n\n\n </body>\n</html>'
ERROR (app) Unable to manage subcloud subcloud1",
"ERROR (app) b'<html>\n <head>\n <title>403 Forbidden</title>\n </head>
\n <body>\n <h1>403 Forbidden</h1>\n Access was denied to this
resource.<br /><br />\n\n\n\n </body>\n</html>'" and
"ERROR (app) Unable to reconfigure subcloud subcloud1"
to
"Access was denied to this resource.
ERROR (app) Unable to manage subcloud subcloud1",
"ERROR (app) Access was denied to this resource." and
"Access was denied to this resource.
ERROR (app) Unable to reconfigure subcloud subcloud1".
