Extend RpmTest

[olenagerasimova]

Test for Rpm have to be extended:

• in doesntBrakeMetadataWhenInvalidPackageSent we have make sure that not only repomd.xml is not changed, but other 3 metadata files: primary, other and filelist. The best way to check it I see is to stash xmls after the first update and compare them against the files after second update with broken package.
• we have to make sure that tempdir is cleaned up after the update
• it's necessary to verify that old (previous) meta xmls are removed (verified by StorageHasMetadata matcher)
• metadata files are stored in the correct location: repodata folder relatively to the prefix (verified by StorageHasMetadata matcher)
• update of the same (with no new/deleted rpms) repository for the second time is successful (covered in updatesDifferentReposSimultaneouslyTwice)
• make sure cleanup is called on different errors (throwsExceptionWhenFullUpdatesDoneSimultaneously and skipsInvalidPackageOnUpdate)

All the check have to made for both batchUpdate and updateBatchIncrementally.
