## What changes were proposed in this pull request?
Add a way to turn off HA loadbalancing based on user agent.
This is done because some non-browser clients such as ODBC drivers do not
honor multiple SET-COOKIE headers in response body. This config is to work
around that issue.
This PR proposed a configuration in HA Provider called
`disableLoadBalancingForUserAgents` which takes a comma separated list of user
agents that should disable the HA loadbalancing ifeature.
Following is an example config
```
<provider>
<role>ha</role>
<name>HaProvider</name>
<enabled>true</enabled>
<param>
<name>HIVE</name>
<value>enableStickySession=true;enableLoadBalancing=true;enabled=true;maxFailoverAttempts=42;failoverSleep=50;maxRetryAttempts=1;disableLoadBalancingForUserAgents=Test
User Agent, Test User Agent2,Test User Agent3 ,Test User Agent4
;retrySleep=1000</value>
</param>
</provider>
```
Default value of
`disableLoadBalancingForUserAgents=ClouderaODBCDriverforApacheHive`
