ganesha: an execute call made with argument 'process_input' that is invalid if call is made to a remote machine

[Ramana Raja]

In the ganesha manager library, an execute call that writes export config files does so by making use of 'process_input' argument. See here,
https://github.com/openstack/manila/commit/559b478e8578ab0bf591d29fcb662a9d7a1158da#diff-ccc750d6512ac97d2a7c2744b0991f1bR231
This argument is supported by processutils's execute() method, used to execute command on local machine and not by processutils's ssh_execute() method, used to execute command on remote machine..
See here,
https://github.com/openstack/oslo.concurrency/commit/be982c56eeb5eb900bfda3375a236bfe425ac200#diff-ef5a9bcb5e6c774f4e9b635c72a4aadcR223
So if the config files are to be written to a remote ganesha server, the execute call made with argument 'process_input' will error out since processutils's ssh_execute() method, which is called for remote execution, does not support that argument.

    ganesha: fix execute call using invalid argument

    An execute call in the ganesha manager module that writes ganesha
    export config files is made with 'process_input' argument. This
    argument is invalid for processutils's ssh_execute() method which is
    used by the execute call to write config files to a remote ganesha
    server node. Fix this by not using the 'process_input' argument instead
    use other arguments that would still enable the execute call to write
    ganesha config files.
