The gem install does this, but the download is slow. Watching the wget progress is more satisfying.

This allows the InstrumenterDecorator to properly log the shard name
Running tests individually works, but running the whole
migration_spec.rb file will recreate the issue _almost_
every time, in a random spec.
Here's the full error and stack trace:
Octopus::Migration should send the query to the correct shard

This keeps the test suite going for most users that won't be using the ibm_db gem
Docker dev system
Check that @config exists. Fixes thiagopradi#413
DB2 ibm_db gem support
ibmdb/ruby-ibmdb#89 Until that issue is officially resolved by IBM, I'm using my local fork for testing Octopus.
This is an oddball bug, deep in the DB2 C library. Disconnecting from the database during the Passenger fork process causes it to hang indefinitely
Since we don't disconnect from DB2, this spec fails.
In many setups, the default master shard might be a different database server in each environment. A single `master_shard` config setting doesn't fit. This patch first checks the shards.yml for `octopus` => Rails env => master_shard for a setting, and still falls back to `octopus` => `master_shard` if it doesn't exist
I cowboyed up a bit too fast on the first fix. This moves the per-environment master_shard selection to its own yaml key
