lvdisplay output result should be refine.

Use lvdispaly to get the detail of the LV, the result of LV create time, host and open will how like below:
LV Creation host, time unknown, unknown

open uknown

Also, some of the key and value have a ":" between them but some of them don't have.
I suggest we should all have a ":"

I think we also need a status of activated or not.
