First off, sorry for the noise. This is a cleaner step of #8508
Found more of a root cause of the open file handles.
After more testing I found that the open file descriptors will still
occur for TCP:// connections to the daemon, causing client and/or daemon
to fail.
The issue was instantiating a new http.Transport on _ever_ client
request. So each instance held the prior connection alive, but was only
ever used once.
By moving it out to the initilization of DockerCli, we can now have
reuse of idled connections. Simplifies the garbage overhead of the
client too, though that's not usually a deal.

In the go stdlib net/http Transport, the used connections are cached
when idled. This behaviour is intended for TCP connections and does not
behave correctly for unix sockets. Despite the
DefaultMaxIdleConnsPerHost being 2, the idled connections are held open
during a session. For large sessions like `docker rm $(docker ps -a -q)`
of thousands of containers, it will cause the client _and_ the server to
open too many fails and have failures.
Having keep alives not used for only unix sockets is a work around for
this stdlib issue.
Also this includes disabling compression when communicating over the
local unix socket too.

lineDelim is used by streamJSON() so it needs to be set

Fixes#8407
Setting Host on URL only works if the Request does not
already have its Host property set.
Note that the API version was also swallowed.

Now that the archive package does not depend on any docker-specific
packages, only those in pkg and vendor, it can be safely moved into pkg.

This is the first of two steps to break the archive package's dependence
on utils so that archive may be moved into pkg. Also, the `Go()`
function is small, concise, and not specific to the docker internals, so
it is a good candidate for pkg.

When user passes an invalid tag to `docker build`
(i.e. `docker build -t abcd:A0123456789B0123456789C0123456789 .`), check the
tag first and terminate-early so user can specify the tag again

When doing `docker start -a` on a container that won't start, terminal
was getting stuck on the attach, even after container removal.

Currently, the HostConfig is only passed from the CLI to Docker only
when issuing a docker create, but not when doing a docker run.
In the near future, in order to allocate ports at creation time rather
than start time, we will need to have the HostConfig readily available
at container creation.
This PR makes the client always pass the HostConfig when creating a
container (regardless of whether it's for a run or create).

`docker events > /tmp/out` should not print control
characters to non-terminal STDOUT.
