Aim repo cloud-storage backups

🚀 Feature

There is no out-of-box support for .aim repository backups. Users have to manually create an archive from repo directory and upload to cloud storage buckets.

Motivation

A single-command backup of aim repos. Pre-defined clear naming/versioning across all repos.

Pitch

Add a CLI commands to backup and restore .aim repo in/from cloud storage. Support S3 and GCS. Backup command must create a snapshot of .aim directory for the given repo path. No need to fallback to the upper directories (search for .aim) as it’s done for other CLI commands.

Alternatives

The process of creating a snapshot and uploading it for backups can be done by simple bash script. However, providing it as out-of-box command as part of Aim CLI is better UX.

I have created a PR for review. Kindly review the PR, and let me know your thoughts on the same. @gorarakelyan @alberttorosyan @SGevorg

I had a few questions/suggestions here:

1. There would be a few parameters that would be taken as input in the cli command such as bucket name(required), region (optional, default region would be picked up from the aws credentials and path (optional, by default it would be the current path). In case the bucket name does not exist in s3, the bucket will be created with the given bucket name and then the backup would be created. Please correct me if I am missing something
2. In order to create a unique folder in the s3 bucket, we can create a name using the current date and timestamp. Please suggest if something else needs to be done.
3. Should we create a zip file of the repo and then upload it or should we upload each file in the repo?
