Database port missing in Magento\TestFramework\Db\Mysql #3529
Description
The methods:
Magento\TestFramework\Db\Mysql::storeDbDump()Magento\TestFramework\Db\Mysql::restoreFromDbDump()
(and perhaps others) are creating mysql / mysqldump commands to be invoked via shell. They make use of the --host command-line switch without adressing a potential (optional) port configuration (--port=#).
The configuration format is:
host[:port]
As the configuration data is taken over unchanged, every configuration with a port given makes these CLI commands fail then.
This flaw blocks users with mysql port configuration making use of the test-suite.
