Release 1.10.0

Backend Changes

Breaking Changes

• Remove cassandra SASI indices (#1328, @black-adder)

Migration Path:

1. Run plugin/storage/cassandra/schema/migration/v001tov002part1.sh which will copy dependencies into a csv, update the dependency UDT, create a new dependencies_v2 table, and write dependencies from the csv into the dependencies_v2 table.
2. Run the collector and query services with the cassandra flag cassandra.enable-dependencies-v2=true which will instruct jaeger to write and read to and from the new dependencies_v2 table.
3. Update spark job to write to the new dependencies_v2 table. The feature will be done in #58.
4. Run plugin/storage/cassandra/schema/migration/v001tov002part2.sh which will DELETE the old dependency table and the SASI index.

Users who wish to continue to use the v1 table don't have to do anything as the cassandra flag cassandra.enable-dependencies-v2 will default to false. Users may migrate on their own timeline however new features will be built solely on the dependencies_v2 table. In the future, we will remove support for v1 completely.
