…ting over manifests Target.keyspace is calculated at the beginning of each restore task run. It is vulnerable for changes occurring during restore process, e.g.: - restore targeting some views is started - target.keyspace excludes restored views (checked via CQL query) - restore is paused - restore is resumed - recalculated target.keyspace no longer excludes restored views Units are calculated only once at the beginning of the restore, so they are not vulnerable to mentioned changes and should be used to determine which tables should be restored. Fixes #4037

This commit adds runPausedRestore function which allows to run restore which is going to be interrupted every specified interval. Pausing after some arbitrary amount of time might seem flaky, but we can't always rely on scyllaclient hooks for pausing restore, as we are biased to where we put them. This commit also alters runPausedRestore to include views in schema and the backup, so that it can test for #4037.
