Enable SLA-aware updates

This patch enables SLA-aware updates.

Following https://reviews.apache.org/r/66716/, tasks may now specify custom SLA
policies that will be respected by the scheduler during maintenance. This patch
integrates into the same system to allow users to specify if they want their
updates to also respect SLA. Please see
https://docs.google.com/document/d/1lCoDyoX26qrGrptrgO7vJHqYR_L2CBRGFIywsAd8uQo/edit?usp=sharing
for a more detailed description.

This patch adds two optional Thrift fields, `slaAware` to `JobUpdateSettings`
and `message` to `JobInstanceUpdateEvent`. These should be forward and
backwards compatible.
