IMPALA-11952 (part 2): Fix print function syntax
Python 3 now treats print as a function and requires
the parenthesis in invocation.
print "Hello World!"
is now:
print("Hello World!")
This fixes all locations to use the function
invocation. This is more complicated when the output
is being redirected to a file or when avoiding the
usual newline.
print >> sys.stderr , "Hello World!"
is now:
print("Hello World!", file=sys.stderr)
To support this properly and guarantee equivalent behavior
between python 2 and python 3, all files that use print
now add this import:
from __future__ import print_function
This also fixes random flake8 issues that intersect with
the changes.
Testing:
- check-python-syntax.sh shows no errors related to print
