This is the first automated GitHub actions workflow, and it simply applies
labels to pull request in a best-effort fashion.

This change adds a layer of abstraction around the internal Docker APIs,
and eliminates all direct dependencies on Dockerfiles in the infrastructure.
A subsequent change will automated the generation of local images (with
efficient caching). Note that this change drops the use of bazel container
rules, as that experiment does not seem to be viable.

Even though the default build option is to use 1.14, we want to be
want to keep the ability to target different Go versions for testing
and in case the new release has bugs.

This will make it easier to notice if a code change causes an existing test to
pass.

Right now, sentry panics in this case:
panic: close of nil channel
goroutine 67 [running]:
pkg/tcpip/transport/tcp/tcp.(*endpoint).listen(0xc0000ce000, 0x9, 0x0)
pkg/tcpip/transport/tcp/endpoint.go:2208 +0x170
pkg/tcpip/transport/tcp/tcp.(*endpoint).Listen(0xc0000ce000, 0x9, 0xc0003a1ad0)

Fixes #2468

This just provides some sane reminders and ticks a box on the GitHub UI. This
change also cleans up the issue template, as there is already an automatic
link to the repository's security disclosure policy.

Even though BoundEndpointAt is not yet implemented for gofer fs, allow path
resolution errors to be returned so that we can jump to tmpfs, where it is
implemented.

This allows us to specify a richer configuration for the issue template, that
effectively moves a lot of the "metadata" from the template itself to the main
issue page.

This change:
- Drastically simplifies the synchronization model: filesystem structure is
both implementation-defined and implementation-synchronized.
- Allows implementations of vfs.DentryImpl to use implementation-specific
dentry types, reducing casts during path traversal.
- Doesn't require dentries representing non-directory files to waste space on a
map of children.
- Allows dentry revalidation and mount lookup to be correctly ordered (fixed
FIXME in fsimpl/gofer/filesystem.go).
- Removes the need to have two separate maps in gofer.dentry
(dentry.vfsd.children and dentry.negativeChildren) for positive and negative
lookups respectively.

See tools/nogo/README.md.
The checkescape tool is able to perform recursive escape analysis, using the
actual generated binary to confirm the results produced by the compiler itself.
As an initial use case, this replaces the manual escape analysis tests used for
go_marshal, and validates that the CopyIn and CopyOut paths will not require
any allocation or stack splits.

Capture a timer's locker for each instance of a CancellableTimer so that
reassigning a tcpip.CancellableTimer does not cause a data race.
Reassigning a tcpip.CancellableTimer updates its underlying locker. When
a timer fires, it does a read of the timer's locker variable to lock it.
This read of the locker was not synchronized so a race existed where one
goroutine may reassign the timer (updating the locker) and another
handles the timer firing (attempts to lock the timer's locker).
Test: tcpip_test.TestCancellableTimerReassignment
