Lost quoting for command line arguments

[holstgr-kaust]

There is an issue with lost quoting using Equalizer apps. For example:

app --arg="quoted∧quoted"

Will become:

ssh ... 'app --arg=quoted∧quoted' ...

Instead of:

ssh ... 'app --arg="quoted∧quoted"' ...

As a result, the app will not run the same way on the different nodes, and various arguments will run as commands and fail.

The 'ssh' command is created in _createRemoteCommand and _launch in Equalizer/eq/server/node.cpp using the SATTR_LAUNCH_COMMAND and CATTR_LAUNCH_COMMAND_QUOTE formatting strings in Equalizer/eq/server/global.cpp.

I think the shell already removes the quotes, so Eq never sees them. We probably need to quote each argument?
