Construct a Telepath Proxy from a link tufo.
Args:
link ((str, dict)): A link dictionary.
Examples:
Get a proxy object, call a function then close the object::
foo = openlink(link)
foo.bar(20)
foo.fini()
Get a proxy object as a context manager, which will result in the object being automatically closed::
with openlink as foo:
foo.dostuff(30)
Returns:
Proxy: A Proxy object for calling remote tasks.
