l3_agent: make process_router more robust

If internal_network_added/removed fails, _sync_routers_task will call
process_router to do fault recovery. Because the port is already
added/removed to/from ri.internal_ports, internal_network_added or
internal_network_removed will not be called again.

The patch fix this issue by calling ri.internal_ports.append/removed
only if internal_network_added/removed succeed. Without the patch,
the added testcases would fail.

Add request timeout handling for Mellanox Neutron Agent

Add request timeout handling for messages sent to eswitch Daemon.
Using configurable number of retries and increasing waiting interval
between retries resend the message.
If request timeout persists, eswitch daemon is not reachable.
In such case, exit the agent process.

Fix unable to add allow all IPv4/6 security group rule

Previously, if one tried to add a rule to allow all ingress ipv4 neutron
would respond that the rule was already part of the security group.
This happened as the filter for querying existing rules uses a wildcard for
remote_group_id thus returning a false match. This patch addresses
this issue.

The comment stating 'DHCP agents needs it.' with regards to the
