15ed7642c9 check all keys are present on every insert with fuzz test 
Let's make sure every insert does still contain all keys. Previously we
did this at the end but it made it hard to debug issues that
`validate_btree` might not encounter.

6eb89ca2a1 Merge 'Add deterministic Clock' from Avinash Sajjanshetty 
Fixes #603
This patch adds a `Clock` trait whose member function `now` returns an
`Instant`. Now in sim, we can nicely make the clock deterministic.
The earlier method `get_current_time` returned `chrono::Local::now()`.
The `Instant` returned by `now` carries the same information.

Closes #1263

This will create the initial index btree and insert whatever relevant
records that need to be inserted, it doesn't handle the case of
inserting new index keys when normal records are created afterwards.
That will prob be added in next PR to keep this one concise.
Limbo will properly use the index in a subsequent query:
