1. Proposed title of this feature request

Able to configure fluentd output plugin for forwarding logs to external endpoints configuring the standby or a weight

2. What is the nature and description of the request?

As an user would like to able to define multiple log endpoints (es , fluentd) to have a high availability on the forwarding stack using the standby or the weight (load balancing).

An example for standby:

<server>
host XX
port 20001
</server>
 
<server>
host YY
port 20001
standby
</server>
</store> 

An example for weight (load balancing):

<server>
host XX
port 20001
weight 60
</server>
 
<server>
host YY
port 20001
weight 40
</server>
</store> 

An example for both (weight and standby):

<server>
host XX
port 20001
weight 60
</server>
 
<server>
host YY
port 20001
weight 60
standby
</server>
</store> 

3. Why does the customer need this? (List the business requirements here)

Maintenance or outage on aggregator fluentd servers or single elastic server causes outage on forwarding logs. It's needed to failover manually at this moment. As a user would like to achieve a more flexible way to provide high availability on forwarding stack.
