Blockstore maintenance (#347) * setting up * Implements timer utility * applies async and cancellation to timer loop * Sets up mocktimer and mockblockstore to set up first maintenance module test * wip: first test that calls blockChecker * wip: adding user type to timer callback * Chronicles doesn't like type-arguments? Disables logging in timer module for now * Implementing block check test for blockMaintainer module * Sets up additional tests for blockmaintainer * Removes generic from timer module. Implements numberOfBlocks per interval in blockMaintainer. * Implements blockMaintainer * Sets up tests for blockChecker * Some comments by Mark * Cleanup repostore tests * Setting up the use of std/times for block TTL tracking * repostore adds expiration timestamp * Defaults the repostore clock to the system clock * Applies updates to repostore interface. * Implements retrieving of block expiration information from repostore * Sets up tests for maintenance module behavior * Implements block maintenance module * Wires maintenance module into codex. Sets up integration tests for block expiration * Sets up test for missing behavior: removing timestamp metadata on block delete * Implements removing of expiration metadata in repoStore * Fixes integration tests for block expiration * Adds block expiration tests to integration test run * Handled some comments by Dmitriy * Review comment by Dmitriy: Removes seq[cid] from runBlockCheck * Review comment by Dmitriy: Moves key formatting methods to keyutils. * Review comment by Dmitriy: Encodes durations using chronos * Fixes conversion of TTL type in conf. * Review comments by Dmitriy * Adds unit tests for keyUtils. * Adds test coverage for exception in maintenance module
