The name 'default' can't be used as a member name because it's a
reserved word in Java. Instead it is defined as isDefault, and its
serialization overrided as "default" using gson's @SerializedName
annotation.
This is inconsistent with other REST APIs, which do not override
such names. For example "isPrivate" is allowed to be serialized
as "is_private".
Also, using @SerializedName means that if we want to move the
DashboardInfo class out to the extension API, we would also need
to introduce a dependency on gson in the extension API.
Remove the annotation and let it be serialized as "is_default".
Adjust the GWT UI to use the new name. Include support for the old
name for backwards compatibility in case the GWT UI and backend
are updated separately.
