Metadata files validation

[olenagerasimova]

We need an instrument to validate metadata files in tests. Let's create corresponding classes in test scope, we need to check:

• metadata is valid xml file
• metadata contains given the number of packages
• metadata has info about given packages

After implementation use these instruments in tests classes.
