Allow partial properties to extend from Properties

For now partial properties (Properties, which are the part of ComponentProperties. For example ConnectionProperties) couldn't extend Properties class.
It should extend ComponentProperties, because ClassCastException is thrown otherwise. For example, here
https://github.com/Talend/tdi-studio-se/blob/1f34e0691fe620253b112df03b433b1a4019ad4e/main/plugins/org.talend.designer.core.generic/src/main/java/org/talend/designer/core/generic/utils/ComponentsUtils.java#L194

But ComponentProperties contain a lot of things, which are redundant for partial properties.
Also services callbacks should be working on Properties and not ComponentProperties.

Properties from component-common project should also extend from Properties class.
