> Create RepeatedKeyInfo structure to be saved in deletedTable

> Key: HDDS-2161
> URL: https://issues.apache.org/jira/browse/HDDS-2161
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Reporter: Dinesh Chitlangia
> Assignee: Dinesh Chitlangia
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.5.0
>
> Time Spent: 2h 40m
> Remaining Estimate: 0h

> Currently, OM Metadata deletedTable stores <Key Name, OMKeyInfo>
> When a user deletes a Key, <key name, omKeyInfo> is moved to deletedTable.
> If a user creates and deletes key with exact same name in quick succession
> repeatedly, then old <key name, omKeyInfo> can get overwritten and we may be
> left with dangling blocks.
> To address this, currently we append delete timestamp to keyname and preserve
> the multiple delete attempts for same key name.
> However, for GDPR compliance we need a way to check if a key is deleted from
> deletedTable and thus given the above explanation, we may not get accurate
> information and it must also confuse the users.
>
> This Jira aims to:
> # Create new structure RepeatedKeyInfo which allows us to group multiple
> KeyInfo which can be saved to deletedTable corresponding to a keyname as
> <KeyName, RepeatedKeyInfo>
> # Due to this, before we move a key to deletedTable, we need to check if key
> with same name exists. If yes, then fetch the existing instance and add the
> latest key to the list, store it back to deletedTable, else create a new
> instance and save to table
