svccoreNode class missing. please get clarity from bug engineer if we need to add svccoreNode also or svccoreCtrl is enough ?

### svccoreCtrlr or svccoreNode excessive entries check

Due to excessive `svccoreCtrlr` or `svccoreNode` managed objects, Apic gui stuck in loading multiple queries.

Due to [CSCws84232][62], the APIC GUI may become unresponsive after login, with dashboards stuck in a continuous “Loading…”state.
Administrators may be unable to access or operate the APIC GUI, potentially impacting day-to-day management or upgrade.

This check will verify the count of the `svccoreCtrlr` Managed Object and raise and alarm with the bug if object count found more than 240. Remove the content or objects of `svccoreCtrlr` or `svccoreNode`. Contact Cisco TAC or upgrade to a release containing the fix for CSCws84232 before proceeding with an upgrade.
