Since 1.9, the following short variant options have been
deprecated in favor of their long variants:
`docker run -c (--cpu-shares)`
`docker build -c (--cpu-shares)`
`docker create -c (--cpu-shares)`
`docker update -c (--cpu-shares)`
However, `-c` is still widely used and is considered as
a convenient option for swarm (see #16271).
This fix undeprecated the command line short
variant options of `-c` and updated the deprecated.md.
