**Describe the solution you'd like**
<!-- A clear and concise description of what you want to happen. -->
The `descheduler` supports limiting the total number of pods evicted per rescheduling cycle. Although there have been a `MaxPodsToEvictPerNode` and `MaxPodsToEvictPerNamespace`, but it is not enough

The `MaxNoOfPodsToEvictTotal` serves to prevent scenarios where an unintended issue, such as a software bug or incorrect usage of Pod Disruption Budgets (PDBs), could result in a substantial number of pods being evicted simultaneously, potentially compromising the availability of services.
