Provide better Hot Rod client socket timeout and retry defaults

The current defaults are:

• Socket timeout = 60 seconds
• Max retries = 10

As a result of these defaults, if the server hangs an operation, it'd take 10 minutes (60 second timeout x 10 retries) for the operation to finally return an exception to the client, which is way too much.

So, these default value should change to be more aggressive: 30 second socket timeout and 3 max retries.
