Since Go 1.7, context is a standard package, superceding the
"x/net/context". Since Go 1.9, the latter only provides a few type
aliases from the former. Therefore, it makes sense to switch to the
standard package.

By replacing grpc with ttrpc, we can reduce total memory runtime
requirements and binary size. With minimal code changes, the shim can
now be controlled by the much lightweight protocol, reducing the total
memory required per container.
When reviewing this change, take particular notice of the generated shim
code.
