luci-base: Add possiblity to set path and timeout of ubus connection

It might happen (e.g. when downloading a large file with low speed
connection) that the ubus connection will time out.
The ubus_connect function allows to specify
ubus socket path and ubus connection timeout
so it should allowed to set these arguments from luci.
