[MuranoPL] the result returned by methods 'putFile' and 'runCommand' is useless

[Dmytro Dovbii]

Two methods 'putFile' and 'runCommand' of class io.murano.configuration.Linux provide the useless result because theirs EPs return only exitCode to MuranoPl code. Due to the fact that `verifyExitcode` option is turned on by default the following code

https://github.com/openstack/murano/blob/master/meta/io.murano/Resources/RunCommand.template#L9

will never be executed in case when some script execution fails, because AgentException will be thrown before execution of this code.

We need to return whole structure containing stdout, stderr and exitcode in these functions and add optional parameters allowing to turn on or off options of scripts (captureStdout, captureStderr, verifyExitcode)

    Return full structure of std info in Linux class methods

    This patch adds to 'putFile' and 'runCommand' methods ability to return
    full structure containing stdout, stderr and exitcode instead of
    returning just exitCode, which worked incorrectly.

    New optional parameter 'options' was added to allow specifing custom
    options execution plans.
