man/docker-run.1: misc fixes 

The list of changes here is too long to be described.

Maybe it's better to just rewrite the page from scratch, but at list this commit
makes some things better than before.

A limit value equal to memory plus swap. Must be used with the **-m**

**--memory-swap**=*number*[*S*]
Combined memory plus swap limit; *S* is an optional suffix which can be one of **b**, **k**, **m**, or **g**.
The format of `LIMIT` is `<number>[<unit>]`. Unit can be `b` (bytes),
`k` (kilobytes), `m` (megabytes), or `g` (gigabytes). If you don't specify a
unit, `b` is used. Set LIMIT to `-1` to enable unlimited swap.
This option can only be used together with **--memory**. The argument should always be larger than that of **--memory**. Default is double the value of **--memory**. Set to **-1** to enable unlimited swap.

Both hostPort and containerPort can be specified as a range of ports.
When specifying ranges for both, the number of container ports in the range must match the number of host ports in the range.

**host**: use the host's UTS namespace inside the container.
**--uts**=*type*
Set the UTS mode for the container. The only possible *type* is **host**, meaning to
use the host's UTS namespace inside the container.
Note: the host mode gives the container access to changing the host's hostname and is therefore considered insecure.
**--privileged**=*true*|*false*
Give extended privileges to this container. The default is *false*.
By default, Docker containers are
“unprivileged” (=false) and cannot, for example, run a Docker daemon inside the
Docker container. This is because by default a container is not allowed to
access any devices. A “privileged” container is given access to all devices.
**--privileged** [**true**|**false**]
Give extended privileges to this container. A "privileged" container is given access to all devices.
When the operator executes **docker run --privileged**, Docker will enable access
to all devices on the host as well as set some configuration in AppArmor to
allow the container nearly all the same access to the host as processes running
outside of a container on the host.
**--read-only**=*true*|*false*

By default a container will have its root filesystem writable allowing processes
to write files anywhere. By specifying the `--read-only` flag the container will have
its root filesystem mounted as read only prohibiting any writes.
