Description

Verifies the number of changes across all interfaces in the Spanning Tree Protocol (STP) topology is below a threshold.

Expected Results
----------------
* Success: The test will pass if the total number of changes across all interfaces is less than the specified threshold.
* Failure: The test will fail if the total number of changes across all interfaces meets or exceeds the specified threshold,
indicating potential instability in the topology.

Fixes #782

Can you add unit tests with outputs from different configured spanning-tree modes (mstp, rapid-pvst, rstp, none)?

DC1-LEAF1A(config)#spanning-tree mode ?
  backup      Backup port mode
  mstp        Multiple spanning tree protocol
  none        Disable spanning tree
  rapid-pvst  Per VLAN rapid spanning tree protocol
  rstp        Rapid spanning tree protocol
