remote_access: Don't force ssh port to 22 if unspecified
It's possible to specify a default port for a DUT in your .ssh/config
file. This is super useful if your setup looks like this:
Local DUT ===Ethernet=== Local computer ===SSH=== Remote Build Machine
In the above scenario if your Local DUT had a local IP address of
192.168.0.59 then you could ssh from the local computer to the remote
build machine with:
ssh -R8022:192.168.0.59:22 remote_build_machine
After doing that, you'd define this in your .ssh/config:
Host my_dut
Port 8022
HostName 127.0.0.1
...and now you can ssh from your Remote Build Machine do your dut with
just "ssh my_dut".
The problem is: if you try to use update_kernel to update the kernel
of that DUT the port will be overridden back to 22. :(
Let's fix remote_access to not override the port unless it was
specified.
BUG=None
TEST=update_kernel
