add noFailFast option to FinagleMysqlContextConfig

[krrrr38]

Problem

Finagle manage clients, but sometimes we want to connect LB. At that time, it is better to set noFailFast. But FinagleMysqlContextConfig.client doesn't have such config.

Usually, it's a good idea to disable Fail Fast for server sets with only one host in the load balancer's replica set.

Solution

Add noFailFast option into FinagleMysqlContextConfig.
