Simplify API / remove legacy functions / methods

[mpenning]

As part of the general API overhaul heading into version 2.0.0, the following legacy methods have been removed.

• ciscoconfparse append_line()
• ciscoconfparse delete_lines()
• ciscoconfparse find_all_children()
• ciscoconfparse find_blocks()
• ciscoconfparse find_children()
• ciscoconfparse find_children_w_parents()
• ciscoconfparse find_lineage()
• ciscoconfparse find_lines()
• ciscoconfparse find_parents_w_child()
• ciscoconfparse find_parents_wo_child()
• ciscoconfparse insert_before()
• ciscoconfparse insert_after()
• ciscoconfparse insert_after_child()
• ciscoconfparse prepend_line()
• ciscoconfparse req_cfgspec_all_diff()
• ciscoconfparse req_cfgspec_excl_diff()
• ciscoconfparse _sequence_parent_lines()
• ciscoconfparse _sequence_nonparent_lines()
• ciscoconfparse sync_diff()
• ConfigList has_line_with()
• ccp_util dns_lookup()
• ccp_util dns6_lookup()
• ccp_util reverse_dns_lookup()
• HDiff()

These APIs were removed to ferret out sub-optimal execution, reduce API overlap, and lower user cognitive load; version 2.0.0 focuses on a leaner API.

These changes will NOT be released on PYPI to maximize compatibility with previous versions. The new API will be released under ciscoconfparse2 as a completely new github project and PYPI release.

See CHANGES.md for details. See the ciscoconfparse page for information on the recommended APIs.
