[ocis] Space Trashbin expiration

[exalate-issue-sync]

Description

User Stories

• As a sysadmin i want to auto clean the trashbin of the users to save storage space

Value

Better Storage usage

Acceptance Criteria

• oCIS tracks the time a file resides in the trashbin
• There is a CLI command that wipes expired trash items which we can trigger via kubernetes tasks
• If a file is restored and then deleted again, the retention time period starts again
• The time period for files in the trashbin can be configured differently on personal spaces and project spaces (default 30 days [~tbaader] please confirm), needs to be possible to deactivate completely
• We have a github issue with technical debt label that tracks changing to service accounts, see Note below.

Notes

When service accounts are available we need to revisit this because currently we have to impersonate the admin, list all spaces, impersonate a manager or owner for each space and then expire the trash.
