Set the OVH username.

You can specify a direct value. For example:

<pre>
.login("foo");
</pre>

<p>
You can also specify one or several property keys. For example:

<pre>
.login("${custom.property.high-priority}", "${custom.property.low-priority}");
</pre>

The properties are not immediately evaluated. The evaluation will be done
when the {@link #build()} method is called.

If you provide several property keys, evaluation will be done on the
first key and if the property exists (see {@link EnvironmentBuilder}),
its value is used. If the first property doesn't exist in properties,
then it tries with the second one and so on.

@param login
one value, or one or several property keys
@return this instance for fluent chaining
