[MRESOLVER-278] BREAKING: Introduce RepositorySystem shutdown hooks

[jira-importer]

Tamas Cservenak opened MRESOLVER-278 and commented

Introduce onSystemShutdown hooks and make following components use these:

• DefaultSyncContext
• GroupId RRF
• SummaryFile TCS

Former will shut down named locks adapter, while latter two are flushing (if recorded!) in this hook. This also implies, that in mvnd for example, daemons needs to be killed to have recorded data saved.
