test_bgp_large_community_topo_1.py: Test BGP large community.

Following tests are covered:
1. Verify the standard large-community-lists can permit or deny
   large community attribute only in the correct canonical format.
2. Verify the expanded large-community-lists can permit or deny
   large community attribute both in the correct canonical format
   as well as REG_EX.
3. Verify that we can modify a large-community-list is in use,
   to add/remove attribute value and it takes immediate effect.
4. Verify that large community attribute gets advertised when
   route-map is applied to a neighbor and cleared when route-map
   is removed.
5. Verify that duplicate BGP Large Community values are NOT be transmitted.
6. Verify if we want to remove all the large-community attributes from a
   set of prefix we can set the value as NONE.
7. Redistribute connected and static routes in BGP process with a route-map
   appending/removing L-comm attributes.
8. Verify if we want to remove specific large-community values from
   a set of prefix we can make use of DELETE operation based on L-comm list.
9. Verify that if community values are NOT be advertised to a specific
   neighbour, we negate send-community command.
   (Send-community all is enabled by default for all neighbors)
10. Verify that large-community lists can not be configured without providing
    specific L-community values(for match/delete operation in a route-map).
11. Verify that Match_EXACT clause should pass only if all of the L-comm
    values configured (horizontally) in the community list is present in
    the prefix.  There must be no additional L-communities in the prefix.
12. Verify that Match_ALL clause should pass only if ALL of the L-comm values
    configured (horizontally) in the community list is present in the prefix.
    There could be additional L-communities in the prefix that are not present
    in the L-comm list.
13. Verify that Match_ANY clause should pass only if at-least any one L-comm
    value configured(vertically) in large-community list, is present in prefixes.
14. Verify large-community lists operation in a route-map with match RegEx
    statements.
