[Feature Request] Add limit on number of processors in Ingest pipelines

[dhwanilpatel]

Is your feature request related to a problem? Please describe

Today there is not any limit on number of processors in ingest pipeline. Due to this user can create too many processors for pipeline which can cause issues in Opensearch. [For e.g. : #6338]

Describe the solution you'd like

Ideally there should be some limit in system for the number of processors as well. We should create the cluster setting for managing this number of processor limit.
