Improvement/cldsrv 548 flag update oplog

[benzekrimaha]

This PR aims to introduce a flag that will be used by Arsenal to introduce a hack to write the MD twice in the oplog: one "deleted: true" copy of the previous MD, followed by the expected update with the new metadata.

The project version will be bumped once arsn released

• This handles the case of bucket without versioning ; we may however have the same issue in version suspended case ? @Kerkesni, is there maybe already a function to check if we are in these kind of condition?
• no reason to check Object.keys(objMD.archive) : we should simply check if the object has been written to "cold", i.e. objMD?.archive?.archiveInfo (and you must not check the content of archiveInfo, it is supposed to stay opaque: hence the type any in arsenal's ObjectMDArchive)

AFAIR, race conditions (e.g. object deleted/replaced/...) during the archival process should be handled already when finishing the transition : if the object does not exist (or etag does not match), backbeat will post a Delete/GC request back to tape I think...

Looking at the function isVersioningEnabled

    isVersioningEnabled() {
        const versioningConfig = this.getVersioningConfiguration();
        return versioningConfig ? versioningConfig.Status === 'Enabled' : false;
    }

This should handle the versioning suspended case also. (returns false when the bucket is non versioned and when it's in versioning suspended mode)
