## Context
As we grow, the messaging scripts are experiencing performance issues
forcing us to temporarily disable them on the cloud.
While investigating the performance, I have noticed that generating the
entity schema (for twentyORM) in the repository is taking ~500ms locally
on my Mac M2 so likely more on pods. Caching the entitySchema then!
I'm also clarifying naming around schemaVersion and cacheVersions ==>
both are renamed workspaceMetadataVersion and migrated to the workspace
table (the workspaceCacheVersion table is dropped).
Closes#6382
Create SetUserVarsAccountsToReconnectCommand.
This command loops on all workspaces and:
- deletes all user vars with deprecated key `ACCOUNTS_TO_RECONNECT`
- creates a key value pair of type `USER_VAR` with a key of
`ACCOUNTS_TO_RECONNECT_INSUFFICIENT_PERMISSIONS` for all connect
accounts with a message channel or calendar channel with status
`FAILED_INSUFFICIENT_PERMISSIONS`
- Refactor calendar modules and some messaging modules to better
organize them by business rules and decouple them
- Work toward a common architecture for the different calendar providers
by introducing interfaces for the drivers
- Modify cron job to use the new sync statuses and stages
