5cab90d270 log: remove log "module" system 
After comtemplation, the complexity of the logging module system
outweighs its usefulness. This changeset removes the system and restores
lighter weight code paths. As a concession, we can always provide more
context when necessary to log messages to understand them without having
to fork the context for a certain set of calls.

9f5182f394 Remove reaper from containerd daemon 
This allows other packages and plugins to easily exec things without
racing with the reaper.

The reaper is mostly needed in the shim but can be removed in containerd
in favor of the `exec.Cmd` apis

74b3cb3391 Fix exit event handling in shim 
Could issues where when exec processes fail the wait block is not
released.

Second, you could not dump stacks if the reaper loop locks up.

Third, the publisher was not waiting on the correct pid.

5764bf1bad cmd/containerd-shim: set GOMAXPROCS to 2 
The shim doesn't need massive concurrency and a bunch of CPUs to do its
job correctly. We can reduce the number of threads to save memory at
little cost to performance.

e8f52c35ce linux/shim: reduce memory overhead by using ttrpc 
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.
