Locking

[markwylde]

I've just implemented locking of a whole collection.

But the lockbase library allows dot notation, and we should be able to implement row and column locking.

• Table locking (client.lock(['users']))
• Row locking (client.lock(['users.uuid-uuid-uuid-uuid']))
• Column locking (client.lock(['users.email']))
• Row and Column locking (client.lock(['users.uuid-uuid-uuid-uuid.email']))
• GetOne and GetAll endpoints for /_/locks
