Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

Refactored the API to more easily accept new endpoints. Added REST,
client, and CLI endpoints for getting logs from a specific task. All
that is needed after this commit to enable arbitrary service log
selectors is a REST endpoint and handler.
Task logs can be retrieved by putting in a task ID at the CLI instead of
a service ID.
