Need to fix LICENSE and NOTICE for next release

[jon-wei]

As brought up during the vote for 0.13.0-incubating, we will need to correct our LICENSE and NOTICE files for the next release.

[jon-wei]

The new web-console has a dependency on Palantir Blueprint (https://github.com/palantir/blueprint/blob/develop/LICENSE) which uses a license based on the Apache license.

This license is not on the list of approved licenses (https://www.apache.org/legal/resolved.html) but the added clause is similar to the BSD 3-clause license which is allowed.

I've opened an Apache LEGAL issue to ask if Blueprint can be included: https://issues.apache.org/jira/browse/LEGAL-436
