Description of Issue/Question
https://github.com/napalm-automation/napalm/blob/develop/napalm/junos/junos.py#L59
In the JunOSDriver() Constructor, there is no way to use huge_tree as an optional arg.
ncclient/ncclient#185 in this issue, whenever an xml node is greater than 10,000,000 bytes, an exception is raised lxml.etree.XMLSyntaxError: xmlSAX2Characters: huge text node
To fix this jnpr.junos.device.Device() introduced a huge_tree parameter here. Juniper/py-junos-eznc#975
But napalm doesn't support the huge_tree parameter yet. Due to this, I am seeing the same exception raised whenever I call get_config()
