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.

Removed erronus config file comment

The comment stating 'DHCP agents needs it.' with regards to the
rpc_notifier notification_driver is incorrect.  Looking through
the code, I see no place this is true.  I believe it to be an
error.

Do not concatenate localized strings

This makes it hard for translators to understand what is going
on. Use string formatting with kwargs expansion.
