[BugFix] Fix duplicate entries in be_logs; Add reset_delvec in script; Add BE id in error message when query failed

[decster]

Why I'm doing:

Their are duplicate entries when using be_logs with '.*' parttern.
There is no be ID in error message when query failed.

What I'm doing:

Fix regex match bug in greplog;
Add BE id in error message;
Add a tool to fix corrupted metadata causing "no delete vector found" error;

Fixes #51190

The most risky bug in this code is:
Potential null pointer dereference in reset_delvec method when tablet->data_dir() returns null. This could cause a segmentation fault.

You can modify the code like this:

static std::string reset_delvec(int64_t tablet_id, int64_t segment_id, int64_t version) {
    auto tablet = get_tablet(tablet_id);
    if (!tablet) {
        return "tablet not found";
    }
    auto data_dir = tablet->data_dir();
    if (!data_dir) {
        return "data directory not found";
    }
    DelVector dv;
    dv.init(version, nullptr, 0);
    auto st = TabletMetaManager::set_del_vector(data_dir->get_meta(), tablet_id, segment_id, dv);
    return st.to_string();
}
