Description

Ext Proc to Support Session Affinity: Add session affinity to http ext_proc

Description: Currently, ext_proc lacks session affinity support. To address this, it should detect if a hash policy is specified in the incoming gRPC initial metadata and apply that policy using the corresponding headers or cookies.
