Container memory limit can be specified in kilobytes, megabytes or gigabytes

    -m 10  # 10 bytes
    -m 10b # 10 bytes
    -m 10k # 10240 bytes (10 * 1024)
    -m 10m # 10485760 bytes (10 * 1024 * 1024)

Units are case-insensitive, and 'kb', 'mb' and 'gb' are equivalent to 'k', 'm' and 'g'.
Update documentation to reflect changes in Config and HostConfig
network: add iptables rules to explicitly allow forwarding

Explicitly enable container networking for Fedora and other distros that
have a REJECT all rule at the end of their FORWARD table.
Update ubuntu packaging script, especially to stop docker group deletion
- Added delete all the containers example
make all image ID and container ID API responses use the Long ID (Closes #2098)
- Updated description
Correctly express "any address" to iptables.

Iptables interprets "-d 0.0.0.0" as "-d 0.0.0.0/32", not /0. This
results in the DNAT rule never matching any traffic if not bound
to a specific host IP.

Fixes #2598
Added status column to API client table
