Retention Governance/"compliance light" mode - Allow for granted users to delete content under retention or legal hold

User story

• As a platform administrator, I want to configure if a granted user can delete a document under retention and/or legal hold.
• As a user with a specific permission and ONLY in case of the retention addon is configured to allow it, I can delete a document under retention or under legal hold, so that I can delete content in case of mistake (wrong retention period) or in case of legal changed with retroactive application.

Description

The goal is to maintain a high level of security by using retention features but with a more flexible mode than the Compliance mode as power users can delete a record under retention or legal hold.

This improvement requires to configure the addon in a specific mode: "Governance" mode and to implement a specific atomic permission: RemoveRecords

Acceptance criteria

When the retention addon is configured in Governance mode:

• As a user with ManageRecord permission, I can NOT delete a document under retention or legal hold
• As a user with write permission but without ManageRecord permission, I can NOT delete a document under retention or legal hold
• As a user with RemoveRecords permission, I can delete a document under retention or legal hold (with confirmation about "record" deletion, UX feedback, this might actually happen by default, but confirm with Carolina Gouveia)
• As an administrator, I can delete a document under retention or legal hold

When the retention addon is NOT configured in Governance mode:

• As a user with ManageRecord permission, I can NOT delete a document under retention or legal hold
• As a user with write permission but without ManageRecord permission, I can NOT delete a document under retention or legal hold
• As a user with RemoveRecords permission, I can NOT delete a document under retention or legal hold
• As an administrator, I can NOT delete a document under retention or legal hold
