Need to add "sudo" prefix to Docker cmd (or other Linux based SSH cmd)

[meirwah]

Since users might use a non root linux user for executing cmd on remote linux machine...

[orius123]

this not always required and can cause regular user not to be able to control the docker componnets. maybe we should make it optional

[meirwah]

of course.. it should optional...
but question is.. what is the default?

@meshipeer There is already an operation https://github.com/CloudSlang/cloud-slang-content/blob/master/content/io/cloudslang/base/os/linux/users/add_user_to_sudoers_list.sl. Taking this in consideration, modifying existing operations that use ssh, will require an optional sudo input which will require an interactive session in which a password will be required. We can discuss this concern offline.
