Add S3 destination to na_elementsw_backup module

[scaleoutsean]

SUMMARY

• There appears to be no S3-related inputs for this module as of mid 2021, so it seems like only SF to SF backups are supported.
• snapshot_id param could be added

ISSUE TYPE

One of two backup destinations is supported - S3/Swift (okay, nobody uses Swift) is not yet, and it requires slightly different input parameters from what is currently available so it appears that the current module cannot work with Backup to S3.

Notice how the API allows the useful snapshot_id param which isn't currently available or exposed in the UI. That could be added both here and to existing (SF to SF) module.

TFM says if snapshot_id = 0, then ad-hoc snapshot is made, but snapshot_id = "" is effectively the same, that's why the current module works fine without it.
