* Micro benchmarks: add support for multiples runtimes

This is the first in a series of micro benchmarks for containerd.
Performance measurement will use containerd objects and methods
that are not dependent on the grpc API and dont require the daemon
to the running. Test will require containerd-shim and runc.
The motivation is to understand the baseline performance at the lowest
containerd layer. A natural extension to this effort would be to write
macro benchmarks which would include API and daemon.
Note:
- Currently measures only one workload (busybox sh) start times. Will
add other bundles and args soon.
- Can use integration-test utils for bundle processing. However, json
marshal/unmarshal is currently timing out standard benchmark times. So
going with default spec for now.
Sample run:
BenchmarkBusyboxSh-4 / # / # / # 2 576013841 ns/op

This removes most of the deps on the larger packages for the shim and
reduces the binary size and memory footprint from a 7.1mb binary to a
2.6mb binary.

This allows us to build a static binary for all three binaries, from the make file using ``make static``.

Convert pids in containerd to string
This is so that we no longer care about linux or system level pids and
processes in containerd have user defined process id(pid) kinda like the
exec process ids that docker has today.

Make sure that the container is actually built before commands in the
Makefile that require doing `docker run` on the devel container.
