New description:
This patch fixes two minor bugs in the poset code.
1. `LatticePoset` should take the same input as Poset. E.g.,
{{{
sage: Poset(cover_relations=True)
Finite poset containing 0 elements
sage: LatticePoset(cover_relations=True)
...
TypeError: LatticePoset() got an unexpected keyword argument
'cover_relations'
}}}
2. The plot for posets does not properly pass the element_label dict to
HasseDiagram.plot.
Depends on #10998
