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.
