The github.com/containerd/containerd/log package was moved to a separate
module, which will also be used by upcoming (patch) releases of containerd.
This patch moves our own uses of the package to use the new module.

Previously, the AWSLogs driver attempted to implement
non-blocking itself. Non-blocking is supposed to
implemented solely by the Docker RingBuffer that
wraps the log driver.

Before this change, the awslogs collectBatch and processEvent
function documentation still referenced the batchPublishFrequency
constant which was removed in favor of the configurable log stream
forceFlushInterval member.

Some packages were using `logrus.Fatal()` in init functions (which logs the error,
and (by default) calls `os.Exit(1)` after logging).
Given that logrus formatting and outputs have not yet been configured during the
initialization stage, it does not provide much benefits over a plain `panic()`.
This patch replaces some instances of `logrus.Fatal()` with `panic()`, which has
the added benefits of not introducing logrus as a dependency in some of these
packages, and also produces a stacktrace, which could help locating the problem
in the unlikely event an `init()` fails.
Before this change, an error would look like:
$ dockerd
FATA[0000] something bad happened
After this change, the same error looks like:
$ dockerd
panic: something bad happened

Added an option 'awslogs-format' to allow specifying
a log format for the logs sent CloudWatch from the aws log driver.
For now, only the 'json/emf' format is supported.
If no option is provided, the log format header in the
request to CloudWatch will be omitted as before.

Loggers that implement BufSize() (e.g. awslogs) uses the method to
tell Copier about the maximum log line length. However loggerWithCache
and RingBuffer hide the method by wrapping loggers.
As a result, Copier uses its default 16KB limit which breaks log
lines > 16kB even the destinations can handle that.
This change implements BufSize() on loggerWithCache and RingBuffer to
make sure these logger wrappes don't hide the method on the underlying
loggers.
Fixes#41794.

TestLogBlocking is intended to test that the Log method blocks by
default. It does this by mocking out the internals of the
awslogs.logStream and replacing one of its internal channels with one
that is controlled by the test. The call to Log occurs inside a
goroutine. Go may or may not schedule the goroutine immediately and the
blocking may or may not be observed outside the goroutine immediately
due to decisions made by the Go runtime. This change adds a small
timeout for test failure so that the Go runtime has the opportunity to
run the goroutine before the test fails.

The CloudWatch Logs API defines its limits in terms of bytes, but its
inputs in terms of UTF-8 encoded strings. Byte-sequences which are not
valid UTF-8 encodings are normalized to the Unicode replacement
character U+FFFD, which is a 3-byte sequence in UTF-8. This replacement
can cause the input to grow, exceeding the API limit and causing failed
API calls.
This commit adds logic for counting the effective byte length after
normalization and splitting input without splitting valid UTF-8
byte-sequences into two invalid byte-sequences.

When then non-blocking mode is specified, awslogs will:
- No longer potentially block calls to logstream.Log(), instead will
return an error if the awslogs buffer is full. This has the effect of
dropping log messages sent to awslogs.Log() that are made while the
buffer is full.
- Wait to initialize the log stream until the first Log() call instead of in
New(). This has the effect of allowing the container to start in
the case where Cloudwatch Logs is unreachable.
Both of these changes require the --log-opt mode=non-blocking to be
explicitly set and do not modify the default behavior.

Log drivers may have an internal buffer size that can be accommodated
by the copier as it is more effective to buffer and send fewer though
larger messages that the log driver can consume.
This eliminates the need for Partial handling for drivers that do not
support the concept (ie: awslogs, which can only have events up to
service limits).
