SCP task should be able to read the ssh config file for proxy settings

Sometimes, users might want to scp some files from bamboo to a target machine that sits behind SSH proxy server.Effectively using the configuration:

bamboo server -->SSH proxy server --> Target server

Normally the SSH proxy configuration will be set in the /<user>/.ssh/config file and this will work from the command line with something like:

scp -P 22 test.txt someuser@target-server:/tmp

However bamboo will fail in the scp task with connection timeout errors due to the proxy not being applied
