config-get command fails config contains certain valid database access parameters
Some valid database access parameters are not handled correctly by the code used to construct JSON text for config-get. The result is a failed command response and error text identifying the "invalid" parameter.
This occurs for the following parameters: request-timeout, max-reconnect-tries, reconnect-wait-time, tcp-keepalive, tcp-nodelay
