[Patch]-Avoid "WARN {VFSTransportListener} -clustering config are not present log when enabling ClusterAware" in MI cluster

[veneerac]

Description

When using the VFS Lister proxy in the MI cluster, it is necessary to configuretransport.vfs.ClusterAware parameter as per the guidelines outlined in [1]. This parameter should be set as follows:

<parameter name="transport.vfs.ClusterAware">true</parameter>

After configuring the cluster and deploying the VFS proxy, the VFS Lister logs warnings on each node. Here are the warning logs:

2023-10-19 17:18:07,124]  WARN {VFSTransportListener} - Although proxy is cluster aware, clustering config are not present, hence running the the polling task in this node

Steps to Reproduce

Steps to re-produce the issue

1. set up two MI cluster nodes.

Deploy the following proxy configuration in MI nodes :

<proxy xmlns="http://ws.apache.org/ns/synapse" name="StockQuoteProxy" transports="vfs">
    <target>
        <inSequence>
	    <log level="custom"> <property value="#############VFS#########" name="log"/> </log>
            <log level="full"/>
        </inSequence>
    </target>
    <parameter name="transport.vfs.FileURI">sftp://user_name:password@<host_name>:<port_number>test/in?transport.vfs.AvoidPermissionCheck=true</parameter>
    <parameter name="transport.vfs.ContentType">text/xml</parameter>
    <parameter name="transport.vfs.FileNamePattern">.*\.xml</parameter>
    <parameter name="transport.PollInterval">15</parameter>
    <parameter name="transport.vfs.ClusterAware">true</parameter>
    <parameter name="transport.vfs.MoveAfterProcess">sftp://user_name:password@<host_name>:<port_number>test/out?transport.vfs.AvoidPermissionCheck=true</parameter>
    <parameter name="transport.vfs.MoveAfterFailure">sftp://user_name:password@<host_name>:<port_number>test/out?transport.vfs.AvoidPermissionCheck=true</parameter>
    <parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter>
    <parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter>
</proxy>

After few seconds, you will notice a continuous WARNING message in the logs, even if your cluster configuration is correct:
WARN {VFSTransportListener} - Although the proxy is cluster-aware, the required clustering configurations are missing, resulting in the execution of the polling task on this node.

WARN {VFSTransportListener} - Although the proxy is cluster-aware, the required clustering configurations are missing, resulting in the execution of the polling task on this node.
