* [HUDI-3029] Transaction manager: avoid deadlock when doing begin and end transactions
- Transaction manager has begin and end transactions as synchronized methods.
Based on the lock provider implementaion, this can lead to deadlock
situation when the underlying lock() calls are blocking or with a long timeout.
- Fixing transaction manager begin and end transactions to not get to deadlock
and to not assume anything on the lock provider implementation.
- Adding Local JVM process based lock provider implementation
- This local lock provider can be used by a single writer process with async
table operations to guard the metadata tabl against concurrent updates.

- Changes the default config of marker type (HoodieWriteConfig.MARKERS_TYPE or hoodie.write.markers.type) from DIRECT to TIMELINE_SERVER_BASED for Spark Engine.
- Adds engine-specific marker type configs: Spark -> TIMELINE_SERVER_BASED, Flink -> DIRECT, Java -> DIRECT.
- Uses DIRECT markers as well for Spark structured streaming due to timeline server only available for the first mini-batch.
- Fixes the marker creation method for non-partitioned table in TimelineServerBasedWriteMarkers.
- Adds the fallback to direct markers even when TIMELINE_SERVER_BASED is configured, in WriteMarkersFactory: when HDFS is used, or embedded timeline server is disabled, the fallback to direct markers happens.
- Fixes the closing of timeline service.
- Fixes tests that depend on markers, mainly by starting the timeline service for each test.

* [HUDI-2443] Hudi KVComparator for all HFile writer usages
- Hudi relies on custom class shading for Hbase's KeyValue.KVComparator to
avoid versioning and class loading issues. There are few places which are
still using the Hbase's comparator class directly and version upgrades
would make them obsolete. Refactoring the HoodieKVComparator and making
all HFile writer creation using the same shaded class.
* [HUDI-2443] Hudi KVComparator for all HFile writer usages
- Moving HoodieKVComparator from common.bootstrap.index to common.util
* [HUDI-2443] Hudi KVComparator for all HFile writer usages
- Retaining the old HoodieKVComparatorV2 for boostrap case. Adding the
new comparator as HoodieKVComparatorV2 to differentiate from the old
one.
* [HUDI-2443] Hudi KVComparator for all HFile writer usages
- Renamed HoodieKVComparatorV2 to HoodieMetadataKVComparator and moved it
under the package org.apache.hudi.metadata.
* Make comparator classname configurable
* Revert new config and address other review comments
