No call_cannoli function

[akmorrow13]

bwa_alignment for cannoli will fail:

from bdgenomics.workflows.tools.spark_tools import call_adam, \
    call_cannoli, \
    call_conductor, \
    MasterAddress, \
    HDFS_MASTER_PORT, \
    SPARK_MASTER_PORT

ImportError: cannot import name call_cannoli

I was thinking it might be on a branch somewhere, but I can't find it.
