Closes#9798
@maintainers please note that this is a change to the UX. We no longer
require the -f flag on `docker tag` to move a tag from an existing image.
However, this does make us more consistent across our commands,
see https://github.com/docker/docker/issues/9798 for the history.

The 1.22 API was temporarily removed in e4d86c2c38f4c99660da8ed65a8103e283e07e23
to prevent it showing up in the 1.9 documentation.
This reverts that change and tweaks the aligning
of the table headers in Markdown source.

Docker daemon uses kv-store as the host-discovery backend.
Discovery module tracks the liveness of a node through a simple
keepalive mechanism. The keepalive mechanism depends on every
node performing heartbeat by registering itself with the discovery
module (via KV-Store Put operation). And for every Put operation,
the discovery module in all other nodes will receive a Watch
notification. That keeps the node alive.
Any node that fails to register itself within the TTL timer is
considered dead and removed from the discovery database.
The default timer (heartbeat = 20 seconds & ttl = 60 seconds)
works fine for small clusters. But for large clusters, these
default timers are extremely aggressive and that causes high CPU
& most of the processing is spent managing the node discovery
and that impacts normal daemon operation.
Hence we need a way to make the discovery ttl and heartbeat
configurable. As the cluster size grows, the user can change
these timers to make sure the daemon scales.

Our tooling used to convert Markdown to HTML doesn't
properly handle '|' symbols embeded in code blocks
inside a table.
Changed the table to a plain HTML table as a workaround.
Also fixed indentation levels of two code examples.

Component: engine
Currently, the Docker repos will trigger apt-get errors on a
multiarch-configured deb system because the repos don't contain all
architectures. For example, on a multiarch system supporting amd64 and
armhf, apt-get will look for armhf Docker packages, fail to find them,
and error out.
Fix this by qualifying the repo line with the currently active
architecture.
This fixes issue #18207.

Original docker `cp` always copy symbol link itself instead of target,
now we provide '-L' option to allow docker to follow symbol link to real
target.
