Owen Diehl 6b4563cd53 Prevent IndexShipper from leaking mutex accesses. (#7548) ... # What Inverts control in the `index-shipper` so consumers don't manage accesses to mutexes. This prevents deadlocks and no longer requires consumers have internal knowledge of the `index-shipper` itself. This PR reverts a few previous attempts. Look at the last commit to see the net-additions. # Background: TSDB previously didn't use mmap, which meant we could freely pass around TSDBs as `[]byte`. Since they were immutable, we didn't need to know when an underlying index was cleaned up/closed; this coordination was unnecessary and the garbage collector would clean up dangling memory for us. After introducing TSDB, we needed to control access to avoid use-after-free bugs. A few attempts at controlling this became increasingly complex & error prone. Instead of requiring _consumers_ to prevent deadlocks on index-shipper internals, it makes more sense that references to the index-shipper's resources should not leak outside the `ForEach` functions that give temporary access to them. This _inverts control_ from the consumer (code which queries the indices) to the producer (the index-shipper). Co-authored-by: Dylan Guedes <djmgguedes@gmail.com>		3 years ago
