> Now the minimum docker version we supported is >=1.0.0. However, we support some advanced
features after docker 1.0.0 as well which require {{Docker::validateVersion}} before use them.
{{Docker::validateVersion}} is a blocking function which waits for {{docker --version}} return.
Call it too many times bring unnecessary overheads. It would be better that we add a member
field represent current docker version in {{Docker}} class to avoid to execute {{docker --version}}
every time.
