> The current update processor chain is rather cumbersome and we should be able to use the updateprocessors without a chain.
> The scope of this ticket is 
> * A new tag {{<updateProcessor>}}  becomes a toplevel tag and it will be equivalent to the {{<processor>}} tag inside {{<updateRequestProcessorChain>}} . The only difference is that it should require a {{name}} attribute. The {{<updateProcessorChain>}} tag will continue to exist and it should be possible to define {{<processor>}} inside as well . It should also be possible to reference a named URP in a chain.
> * processors will be added in the request with their names . Example {{processor=a,b,c}} , {{pre-processor=p,q,r}} or {{post-processor=x,y,z}} . This creates an implicit chain of the named URPs the order they are specified
> * There are multiple request parameters supported by update request 
> ** pre-processor : This chain is executed at the node that receives the request. Other nodes will not execute this
> ** processor : This chain is executed executed at the leader right before the LogUpdateProcessorFactory + DistributedUpdateProcessorFactory . The replicas will not execute this. 
> ** post-processor : This chain is executed right before the RunUpdateProcessor in all replicas , including the leader
> * What happens to the update.chain parameter ? {{update.chain}} will be honored . The implicit chain is created by merging both the update.chain and the request params. {{post-processor}} will be inserted right after the DistributedUpdateProcessor in the chain.   and {{processor}} will be inserted right in the beginning of the update.chain
