[Collections] - Delta recovery + rebalance fails with complete_delta_recovery_failed

Script to Repro

guides/gradlew --refresh-dependencies testrunner -P jython=/opt/jython/bin/jython -P 'args=-i /tmp/win10-bucket-ops.ini rerun=False,quota_percent=95,crash_warning=True -t bucket_collections.collections_rebalance.CollectionsRebalance.test_data_load_collections_with_graceful_failover_recovery,nodes_init=5,nodes_failover=1,recovery_type=delta,override_spec_params=durability;replicas,durability=MAJORITY_AND_PERSIST_TO_ACTIVE,replicas=2,bucket_spec=multi_bucket.buckets_all_membase_for_rebalance_tests_with_ttl,data_load_spec=ttl_load1,data_load_stage=during,skip_validations=False,rerun=False'

Steps to Repro
1) Create a 5 node cluster
2021-02-10 04:11:54,838 | test | INFO | pool-1-thread-6 | [table_view:display:72] Rebalance Overview
-----------------------++-------------------------------------------------

-----------------------++-------------------------------------------------

-----------------------++-------------------------------------------------

2) Create buckets/scopes/collections/data
2021-02-10 04:17:26,428 | test | INFO | MainThread | [table_view:display:72] Bucket statistics
-----------------++--------------------------------------------------------------

-----------------++--------------------------------------------------------------

-----------------++--------------------------------------------------------------

3) Hard failover a node(172.23.120.206)

2021-02-10 04:17:35,237 | test  | INFO    | MainThread | [collections_rebalance:rebalance_operation:545] failing over nodes [ip:172.23.120.206 port:8091 ssh_username:root]

2021-02-10 04:21:47,165 | test  | WARNING | MainThread | [rest_client:get_nodes:1697] 172.23.120.206 - Node not part of cluster inactiveFailed

4) Do delta recovery + rebalance
2021-02-10 04:22:07,907 | test | INFO | pool-1-thread-7 | [table_view:display:72] Rebalance Overview
-----------------------++-------------------------------------------------

Rebalance fails as shown below.
on 172.23.98.196

Haven't seen this failure before. I saw lot of test failures that involve delta recovery + rebalance tests fail because of this.
