Zoltan Borok-Nagy de7f09d726 IMPALA-7644: Hide Parquet page index writing with feature flag
This commit adds the command line flag enable_parquet_page_index_writing
to the Impala daemon that switches Impala's ability of writing the
Parquet page index. By default the flag is false, i.e. Impala doesn't
write the page index.

This flag is only temporary, we plan to remove it once Impala is able to
read the page index and has better testing around it.

Because of this change I had to move test_parquet_page_index.py to the
custom_cluster test suite since I need to set this command line flag
in order to test the functionality. I also merged most of the test cases
because we don't want to restart the cluster too many times.

I removed 'num_data_pages_' from BaseColumnWriter since it was rather
confusing and didn't provide any measurable performance improvement.

This commit fixes the ASAN error produced by the first IMPALA-7644
commit which was reverted later.
