This commit adds an integration test framework for FUSE support. Please
refer to the test example and test/fuse/README.md for further details.
Fixes #3098

- Exclude flaky tests.
- Bump timeout.
- Un-exclude passing tests to increase testing surface.
- Create/Update bugs for tests that pass on runc but fail on runsc.

This change adds a new reverse HTTP test where the HTTPD server runs
in a native container but the client runs inside gVisor. It allows
us to test download performance under varying levels of concurrency.
Also tweaks the concurrent request numbers to test for high levels
of concurrency.

Before kernel version 4.16-rc6, fuse mount is protected by
capable(CAP_SYS_ADMIN). After this version, it uses
ns_capable(CAP_SYS_ADMIN) to protect. Before the 4.16 kernel,
it was not allowed to mount fuse file systems without the
global CAP_SYS_ADMIN.
Fixes #3360

A new network namespace has only the local route table.

- Added a bunch of helpful options which help in speeding up the test and
providing useful output.
- Unexcluded passing tests and updated bugs. Excluded tests which were failing.
- Increased the batch size for java tests so that we can take advantage of
the shared JVMs.
The running time of the tests decreased from 3+ hours (I don't know the exact
running time because this test has always timed out after 3 hours) to 1 hour
15 minutes. We can reliably run this a CI kokoro job.

Envoy (#170) uses this to get the original destination of redirected
packets.

This change:
- Ports the nginx benchmark.
- Switches the Httpd benchmark to use 'hey' as a client.
- Moves all parsers to their own package 'tools'.
Parsers are moved to their own package because 1) parsing output of a command
is often dependent on the format of the command (e.g. 'fio --json'), 2) to
enable easier reuse, and 3) clean up and simplify actual running benchmarks
(no TestParser functions and ugly sample output in benchmark files).

9P2000.L is silent as to how readdir RPCs interact with directory mutation. The
most performant option is for Treaddir with offset=0 to restart iteration,
avoiding needing to walk+open+clunk a new directory fid between invocations of
getdents64(2), and the VFS2 gofer client assumes this is the case. Make this
actually true for the runsc fsgofer.

Return on success should be 0, not size of the struct copied out.

- Unexported some passing tests. This will increase the testing surface and
will be especially helpful when this is enabled for vfs2.
- Run tool tests with -v (verbose output). We only print the output when a test
fails so this should not clutter the output.
- Run tool tests with "-no-rebuild" flag.
- Surround test name with appropriate regex, i.e. ^testname$. This will ensure
that only that test is run. Earlier running go_test:os would also run
go_test:os/exec, go_test:os/signal, go_test:os/user. This should help speed
up the tests as we do not run the same test multiple times anymore.
- Updated bugs.

Compare Linux's fs/eventpoll.c:do_epoll_ctl(). I don't know where EPOLLRDHUP
came from.

We skip gVisor tests for now, as ip6tables aren't yet implemented.

Storing *testing.T on test helper structs is problematic when
subtests are used, because it is possible for nested tests to call
Fatal on parent test, which incorrect terminates the parent test.
For example
func TestOuter(t *testing.T) {
dut := NewDUT(t)
t.Run("first test", func(t *testing.T) {
dut.FallibleCall()
})
t.Run("second test", func(t *testing.T) {
dut.FallibleCall()
}
}
In the example above, assuming `FallibleCall` calls `t.Fatal` on the
`t` it holds, if `dut.FallibleCall` fails in "first test", it will
call `Fatal` on the parent `t`, quitting `TestOuter`. This is not a
behavior we want.

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.

... when it is possible.
The guitar gVisorKernel*Workflow-s runs test with the local execution_method.
In this case, blaze runs test cases locally without sandboxes. This means
that all tests run in the same network namespace. We have a few tests which
use hard-coded network ports and they can fail if one of these port will be
used by someone else or by another test cases.

Copy the list of tags when passing it to _syscall_test.

Sending UDP packets in a loop can be done in a separate goroutine. We
can't do this in ContainerAction because the container will terminate
early.
Locally, scripts/iptables_tests.sh runs ~40 seconds faster.

Allow FUSE filesystems to be mounted using libfuse.
The appropriate flags and mount options are parsed and
understood by fusefs.
