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.

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.

Merge pull request #1779 from AkihiroSuda/resolve-util-bin 
shim: support non-default binary name

7ef4aa5c25 shim: support non-default binary name 
The binary name used for executing "containerd publish" was hard-coded
in the shim code, and hence it did not work with customized daemon
binary name. (e.g. `docker-containerd`)

This commit allows specifying custom daemon binary via `containerd-shim
-containerd-binary ...`.
The daemon invokes this command with `os.Executable()` path.

api: use weak imports for plugin protobufs 
Because of a side-effect import, we have the possibility of pulling in
several unnecessary packages that are used by the plugin and not at
runtime to implement protobuf structures. Setting these imports to
`weak` prevents this from happening, reducing the total import set,
reducing memory usage and binary size.

api/events: split event types from events service 
To avoid importing all of grpc when consuming events, the types of
events have been split in to a separate package. This should allow a
reduction in memory usage in cases where a package is consuming events
but not using the gprc service directly.
