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.

`docker events > /tmp/out` should not print control
characters to non-terminal STDOUT.
This addresses commit 26b4a4920adca614f6be17a96f254f331271faf0
without creating regression described in issue #6509.

--help and help are successful commands so output should not go to error.
QE teams have requested this change, also users doing docker help | less
or docker run --help | less would expect this to work.
Usage statement should only be printed when the user asks for it.
Errors should print error message and then suggest the docker COMMAND --help
command to see usage information.
The current behaviour causes the user to have to search for the error message
and sometimes scrolls right off the screen. For example a error on a
"docker run" command is very difficult to diagnose.
Finally erros should always exit with a non 0 exit code, if the user
makes a CLI error.

If I do a
docker events > /tmp/out
I do not want the control characters getting written to the file.
The check should check the output file not the input file.
