The "password" parameter of std.ssh action has to be specified although it's optional

[Renat Akhmerov]

When using std.ssh with empty password we still have to specify it with an empty value.

Example

action: std.ssh username="myuser" cmd="ls -l"

doesn't work.

But

action: std.ssh username="myuser" password="" cmd="ls -l"

works.
