Add portforward comand so that we can use runsc to forward connections
to container ports. This will eventually be supported in k8s.

Add the usage benchmark which queries memory usage from the container. This
is meant to replace the size benchmark which has a ton of noise.
Flakes are due to the complicated measurement technique of dropping caches ->
parse /proc/meminfo -> start containers -> drops caches again -> parse
/proc/meminfo -> take the diference. This was done because not all runtimes
support docker/containerd stats.
Buuuut...gVisor does, so we'll just take the stats figures to reduce noise
for the memory usage benchmark.
In addition, the returned types.StatsJSON object contains several useful stats
like page faults and CPU usage, so adding these will be trivial and will not
slow down benchmark performance.

Without this, attempting to build or test gVisor on machines where the default
runtime isn't `runc` may fail, as that runtime may not support what we need.

Fix issue with iperf where b.N wasn't changing across runs.
Also, if the given runtime is runc/not given, don't run a profile against it.
PiperOrigin-RevId: 357231450
This includes minor fix-ups:
* Handle SIGTERM in runsc debug, to exit gracefully.
* Fix cmd.debug.go opening all profiles as RDONLY.
* Fix the test name in fio_test.go, and encode the block size in the test.

- Tweak the benchmarks to work with b.N where appropriate. In many cases,
b.N was simply being ignored. This creates an implicit dependency in the
user passing a reasonable benchtime (less than or equal to the actual
runtime of the test, or using the X syntax) otherwise the test runs
forever.
- In cases where the above is impossible, explicitly set benchtime from
the test wrapper, to prevent the above behavior (tensorflow).
- Drop the *Reverse variants, which are simply hey benchmarks. We should
just add a hey benchmark. The platforms benchmarks already include a
native platform, and thus these benchmarks are incredibly confusing.
(In other words, BenchmarkNginxReverse has nothing to do with an nginx
benchmark for runsc.)
- Remove the redunant Harness object, which contains no state, in order
to slightly simplify the code.
- Make Block and Heap profiling actually work, but setting appropriate
runtime parameters (and plumbing them through the config).
- Split the profiling into two phases: start and stop, since some will
need to be started early, and others will need to happen at the end.

Adds profiling with `runsc debug` or pprof to dockerutil. All
targets using dockerutil should now be able to use profiling.
In addition, modifies existing benchmarks to use profiling.
