Update NFS mount settings for GI and DST agents

As of version 13 build 51, there is no UI or REST API routine to update NFS mount options for existing agent.

Current workaround requires manual update of H2 database.

GI Agent:

--GET REQUIRED AGENT_ID
SELECT * FROM PUBLIC.GI_AGENTS;

--Update "MOUNTOPT" coulumn with required options
UPDATE PUBLIC.GI_AGENTS SET MOUNTOPT = '-o rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,nolock,actimeo=0,noac'
WHERE ID = '<GI_AGENT_ID>';

DST Agent:

--GET REQUIRED AGENT_ID
SELECT * FROM PUBLIC.DST_AGENTS;

--Update "MOUNTOPT" coulumn with required options
UPDATE PUBLIC.DST_AGENTS SET MOUNTOPT = '-o rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,nolock,actimeo=0,noac'
WHERE ID = '<DST_AGENT_ID>';
