This non-standard handling for these options was added in [moby@e4c1f07]
and [moby@abe32de] to work around a regression in Docker 1.13 that caused
`docker-machine` to fail. Preserving quotes in such cases is expected (and
standard behavior), but versions of Docker before 1.13 used a custom "mflag"
package for flag parsing, and that package contained custom handling for
quotes (added in [moby@0e9c40e]).
Given that Docker Machine reached EOL a long time ago and other options,
such as `docker context`, have been added to configure the CLI to connect
to a specific host (with corresponding TLS configuration), we can remove
the special handling for these flags, as it's inconsistent with all other
flags, and not worth maintaining for a tool that no longer exists.

CommonOptions was inherited from when the cli and daemon were in the same
repository, and some options would be shared between them. That's no longer
the case, and some options are even "incorrect" (for example, while the
daemon can be configured to run on multiple hosts, the CLI can only connect
with a single host / connection). This patch does not (yet) address that,
but merges the CommonOptions into the ClientOptions.
An alias is created for the old type, although it doesn't appear there's
any external consumers using the CommonOptions type (or its constructor).
