Tim Armstrong c187601b0f Remove Python 2.4 workarounds in start-impala-cluster.py ...

The workarounds are:
* Trying to handle the json module not being present. That module was
  added in Python 2.6 and also isn't used in this file!
* Trying to handle import failure of ImpalaCluster. It appears that
  this is be a workaround for the script being run without the
  correct PYTHONPATH (set by set-pythonpath.sh) - see IMPALA-7989.
  This is fixed in this patch by sourcing it in
  bin/impala-python-common.sh

Testing:
Ran a build on CentOS 6 with Python 2.4 and confirmed that
it was able to start the cluster OK.

Reran a build that previously failed with the python import error.
