Manually lock outgrown enterprise accounts

[vinibrsl]

Changes

This pull request adapts the account locking and grace period flow to enterprise customers. A quick summary of the changes:

• Enables the grace period mechanism for enterprise accounts on Workers.CheckUsage, therefore showing existing dashboard alerts
• Creates a manual_lock field in the grace_period JSON, that when true, does not expire the grace period automatically, therefore preventing Workers.LockSites to lock enterprise customers
• Adds a lock/unlock button to the internal CRM users page
• Tests new existing and new functionality

I recorded this screencast previewing the feature. There's been some refactoring, so small commits can help reviewing.
