Improve batch insertion performance

                 Key: OPENJPA-2017
             Project: OpenJPA
          Issue Type: New Feature
          Components: kernel
    Affects Versions: 2.1.1
            Reporter: Pinaki Poddar
            Assignee: Pinaki Poddar
             Fix For: 2.1.1

Batch loading data is a common use case. Often, the user would not refer to the managed instances
after the loading session. However, the runtime, by default, spends time in detaching the
managed instances by creating/removing proxy or retaining state as per the configured options.

An option should be provided to bypass these operations per persistence context basis.

AutoDetach.NONE could be a possibility. This option will be exclusive i.e. it can not be specified
with any other AutoDetach options. The NONE option will bypass proxying the fields at the
transaction boundary or close.
