* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

- Today, base files have bloom filter at their footers and index lookups
  have to load the base file to perform any bloom lookups. Though we have
  interval tree based file purging, we still end up in significant amount
  of base file read for the bloom filter for the end index lookups for the
  keys. This index lookup operation can be made more performant by having
  all the bloom filters in a new metadata partition and doing pointed
  lookups based on keys.

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Adding indexing support for clean, restore and rollback operations.
   Each of these operations will now be converted to index records for
   bloom filter and column stats additionally.

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Making hoodie key consistent for both column stats and bloom index by
   including fileId instead of fileName, in both read and write paths.

 - Performance optimization for looking up records in the metadata table.

 - Avoiding multi column sorting needed for HoodieBloomMetaIndexBatchCheckFunction

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - HoodieBloomMetaIndexBatchCheckFunction cleanup to remove unused classes

 - Base file checking before reading the file footer for bloom or column stats

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Updating the bloom index and column stats index to have full file name
   included in the key instead of just file id.

 - Minor test fixes.

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Fixed flink commit method to handle metadata table all partition update records

 - TestBloomIndex fixes

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - SparkHoodieBloomIndexHelper code simplification for various config modes

 - Signature change for getBloomFilters() and getColumnStats(). Callers can
   just pass in interested partition and file names, the index key is then
   constructed internally based on the passed in parameters.

 - KeyLookupHandle and KeyLookupResults code refactoring

 - Metadata schema changes - removed the reserved field

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Removing HoodieColumnStatsMetadata and using HoodieColumnRangeMetadata instead.
   Fixed the users of the the removed class.

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Extending meta index test to cover deletes, compactions, clean
   and restore table operations. Also, fixed the getBloomFilters()
   and getColumnStats() to account for deleted entries.

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Addressing review comments - java doc for new classes, keys sorting for
   lookup, index methods renaming.

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Consolidated the bloom filter checking for keys in to one
   HoodieMetadataBloomIndexCheckFunction instead of a spearate batch
   and lazy mode. Removed all the configs around it.

 - Made the metadata table partition file group count configurable.

 - Fixed the HoodieKeyLookupHandle to have auto closable file reader
   when checking bloom filter and range keys.

 - Config property renames. Test fixes.

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Enabling column stats indexing for all columns by default

 - Handling column stat generation errors and test update

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Metadata table partition file group count taken from the slices when
   the table is bootstrapped.

 - Prep records for the commit refactored to the base class

 - HoodieFileReader interface changes for filtering keys

 - Multi column and data types support for colums stats index

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - rebase to latest master and merge fixes for the build and test failures

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups

 - Extending the metadata column stats type payload schema to include
   more statistics about the column ranges to help query integration.

* [HUDI-1295] Metadata Index - Bloom filter and Column stats index to speed up index lookups
