scimage: copy scimage.py to scimage_11_10.py

In preparation for updating scimage.py for latest Ubuntu 12.04 (precise)
scimage: add method to recompile/install openblas
scimage: update hadoop to cdh3u5
scimage: add mosh to default packages
scimage: use custom openblas with NumPy/SciPy
scimage: update header comments for 12.04 (precise)
scimage: remove redundant git install

git is already installed in the install_default_packages method
scimage: add default-jdk to default package list
scimage: fix typo in default package list
scimage: remove pyzmq==2.1.9 requirement

This was a bug in IPython's version checking that appears to be fixed in
0.13.
scimage: update MOTD for latest 12.04 AMIs
scimage: update chroot mounting instructions

Include dbus mount which is necessary in order to upgrade dbus within a
Ubuntu chroot. Also add instructions for mounting sysfs and devpts.
scimage: disable upstart during build

Disabled as a part of setup_environ() and re-enabled in cleanup()
scimage: install missing libltdl dep for condor

The deb package must be manually downloaded to /usr/local/src for now.
scimage: build OpenBlas with NO_AFFINITY=1

NO_AFFINITY=1 is required to utilize all cores on all non
cluster-compute/GPU instance types due to the shared virtualization
layer not supporting processor affinity properly. However, Cluster
Compute/GPU instance types use a near-bare-metal hypervisor which *does*
support processor affinity. From minimal testing it appears that there
is a ~20% increase in performance when using affinity on cc1/cg1 types
implying NO_AFFINITY=1 should *not* be set for cluster compute/GPU AMIs.
scimgdeploy: pep8 cleanup
scimage: add mpich2 to default package list
scimage: install condor-7.7.2-1 and hold version

condor-7.7.2-1 is currently the only version I can get to work as
expected with Ubuntu 12.04
scimage: 'hold' custom versions of OpenBLAS

OpenBLAS has been custom compiled for EC2. Hold the custom version of
OpenBLAS so that it's not upgraded to a new unoptimized upstream
version.
scimage: 'hold' custom OpenMPI build

This prevents the custom OpenMPI build (with SGE support) from being
overwritten by a newer upstream version.
