json: increase the json rpc client value limit

Browse Source 
The jsonrpc client has a limit of 1024 JSON values per
request which is hardly enough for any meaningful config.
For example, calling getbdevs for 24 NVMe drives require
~2300 JSON values.
I kept the original 1024 limit for the RPC server where
it makes sense to have a smaller limit and introduced
a seperate limit for the client.
