> HBaseTestingUtility#waitUntilAllRegionsAssigned(final TableName tableName) hard coded
60 seconds wait for region assignment in a table.  This could cause flaky tests, as the caller
could create table with longs of region which takes longs time; or in CM, RS unavailable could
slow down assignment; or in a slow machine, IT might take long to assign regions.  
> In HBaseAdmin.java, we use a configurable value to wait for the table DDLs: {{this.syncWaitTimeout
= this.conf.getInt("hbase.client.sync.wait.timeout.msec", 10 * 60000); // 10min}} - we should
use the config for the HBaseTestingUtility#waitUntilAllRegionsAssigned() too.
> Of course, the caller could use the "public void waitUntilAllRegionsAssigned(final TableName
tableName, final long timeout)"; but it requires test change (currently, no test directly
calls this signature). 
> {code}  
> /**
>    * Wait until all regions for a table in hbase:meta have a non-empty
>    * info:server, up to 60 seconds. This means all regions have been deployed,
>    * master has been informed and updated hbase:meta with the regions deployed
>    * server.
>    * @param tableName the table name
>    * @throws IOException
>    */
>   public void waitUntilAllRegionsAssigned(final TableName tableName) throws IOException
{
>     waitUntilAllRegionsAssigned(tableName, 60000);
>   }
