Upgrading directly from 0.9.6.1 to 0.11.0 fails

[gunnaraasen]

Steps to reproduce

1. Install 0.9.6.1 and run influx_stress
2. Stop InfluxDB then restart and stop it again to force a WAL flush
3. Install 0.11.0 and run:

$ go/bin/influx_tsm -backup .influxdb-backup .influxdb/data

b1 and bz1 shard conversion.

Note that rolling back to 0.10.3, converting shards, and then upgrading to 0.11.0 again does work.

I don't think there's much we can do about this. The code to support b1 and bz1 doesn't exist anymore, except for a stripped-down version required to convert shards in the 0.10 releases.

To upgrade to InfluxDB 0.11, you must be on version 0.10 and all shards must be in TSM format (the default storage engine starting with InfluxDB 0.10).

So there's no straightforward way to upgrade from 0.9.X to 0.11.
