[DmytroMuravskyi]

BACKGROUND:

• Since Elements is now in 2.0 alpha stage, it's good opportunity to remove obsolete items, I introduced.

DESCRIPTION:

• Message: removed obsolete FromLine method.
• AdaptiveGrid: removed obsolete TryGetVertexIndex with tolerance parameter.
• EdgeInfo: obsolete attribute is removed from HasVerticalChange property.
• RoutingConfiguration: removed obsolete MainLayer and LayerPenalty properties.

TESTING:

• No impact on Elements tests.

FUTURE WORK:

• Removed methods and properties must be removed from downstream repos in order to use Elements 2.0

REQUIRED:

• All changes are up to date in CHANGELOG.md.

COMMENTS:

• Any other notes.
