[TimeEngineer]

The following commands must be implemented:

• CLI: list-devices #5747
• CLI: create-organization #5909
• CLI: bootstrap-organization #5910
• CLI: run-testenv #5911
• CLI: cancel-invitation #6064
• CLI: claim-invitation #6022
• CLI: export-recovery-device #6070
• CLI: greet-invitation #6023
• CLI: import-recovery-device #6072
• CLI: invite-device #5984
• CLI: invite-user #5994
• CLI list-invitations #6067
• CLI: create-workspace #6094
• CLI: list-workspaces #6096
• CLI: share-workspace #6098
• reencrypt_workspace (no longer needed because of the realm_rotation)
• CLI: remove-device #6074
• CLI: stats-organization #6078
• CLI: stats_server #6080
• CLI: status-organization #6083
• rsync (was made for a specific need but it is not really used, so we'll not to migrate it for the moment)
• human_find (I think this is not needed to implement, because not in APIv4)
• CLI: Add build and run instructions in a README.md #6046 (closed as not planned)
