ReMerge branch 'jayeshkrishna/share/spio_add_adiosc_iotype' into next…

… (PR #6738)

Adding support for ADIOS builds with BLOSC in FindPIO
CMake module

Adding preliminary support for ADIOS output compression
and updating to SCORPIO v1.6.6 (which includes patch
to support the new I/O type to use for data compression)

Modifying CIME config and scripts to support writing
ADIOS output files with data compression. A new I/O
type is added to support writing output in ADIOS BP file
format with data compression.

However users would need to move to SCORPIO
master to write ADIOS output with data compression

Note: Writing ADIOS output with data compression is
now supported in SCORPIO master but is not
included in SCORPIO v1.6.6. A future release of
SCORPIO will include this feature
