manifest: add support for revision in include

Attribute groups can now be added to manifest include, thus
all projects in an included manifest file can easily modify
default branch without modifying all projects in that manifest file.

For example,
the main manifest.xml has an include node contain revision attribute,
```
<include name="include.xml" revision="r1" />
```
and the include.xml has some projects,
```
<project path="project1_path" name="project1_name" revision="r2" />
<project path="project2_path" name="project2_name" />
```
With this change, the final manifest will have revision="r1" for project2.
```
<project name="project1_name" path="project1_path" revision="r2" />
<project name="project2_name" path="project2_path" revision="r1" />
```

Test: added unit tests to cover the inheritance
