Remove most shadow relocates
...
Shadow relocates are no longer needed because of our new bootstrapping
process.
It's no longer possible for agent dependencies to interfere with the
user's classpath.
The immediate reason for this change is a bug created in the Cassandra
instrumentation.
The Cassandra instrumentation references guava transitive deps from
the datastax driver. These references are re-written by shadow,
causing the instrumentation to reference 'datadog.agent.deps.google.*'
instead of the guava class.
