Memory leak caused by default initialisation of xlib

[tenxliviu]

Hello,

I managed to find a memory leak caused by "longjohn", a dependency loaded by default through xlib.

What fixed it was configuring xlib in production mode:

global.__xlibInitArgs = Object.assign({ envLevel: 'PROD', logLevel: 'ERROR' }, global.__xlibInitArgs);

I suggest to modify the phanthomjscloud initialisation of xlib to also contain the two parameters above.

thank you for this. I will work on the required change. it is a little difficult because internally we are using a new version of xlib but that is not yet reflected in the public version of phantomjscloud-node. So it may be easier to just update to the newset xlib (and make sure the problem doesn't occur) than it is to fix this.

This is scheduled to get fixed during the coming week.
