Add laminate option to CI tests

CamStan commented 2 years ago

Description

This adds an option to the CI test suites to allow for laminating files when testing. Note: The testing suite is now no longer laminating in any of the tests as some bugs appear to have crept in, causing tests to fail in a few cases (issues #698 and #699). Will add these cases as bugs are addressed.

Update: Issue 698 was resolved and tests that use the --laminate option have been added

Also adds a set of writeread CI tests that shuffle the I/O when using MPI-IO.

Updates docs

Motivation and Context

A recent update changed the behavior of the example programs to no longer laminate by default.

How Has This Been Tested?

Running CI tests on 4 nodes with 2ppn

Once #701 is merged, I can rebase this and add the actual running of the laminate tests to this.
