NC | lifecycle | _parse_key_from_line remove redundant / at the beginning of the file key

[romayalon]

Describe the Problem

If bucket path is configured without trailing '/', _parse_key_from_line() return a key that contained starting '/' which caused an error when trying to delete the object due to re-check of the prefix.

Explain the Changes

1. On _parse_key_from_line() - Added trailing '/' when removing the bucket path.

Issues: Fixed #xxx / Gap #xxx

1. Gap - add auto tests

Testing Instructions:

1. Manual -
2. create a bucket configured with a path without a trailing /.

noobaa-cli bucket update --name bucket10 --path /mnt/gpfs0/romy/demo/bucket10
mkdir /mnt/gpfs0/romy/demo/bucket10/data/
for i in {1..10} ; do touch -d  "10 days ago"  /mnt/gpfs0/romy/demo/bucket10/logs/file${i}.txt ; done
noobaa-cli lifecycle --disable_runtime_validation
