Add code to find and delete an existing backup file in a Backblaze B2 bucket before uploading a new backup file

Browse Source 
This commit modifies the upload_to_b2 method in the MysqlDatabaseBackup class to search for an existing backup file with the same name as the backup file being uploaded in a specified Backblaze B2 bucket. The implementation retrieves a list of all files in the bucket using the b2 ls command and then iterates over each line to search for a file with the same name as the backup file. If a matching file is found, the implementation extracts its file ID using a regular expression and then uses the b2 delete-file-version command to delete the file from the bucket. Note that this implementation assumes that the backup file has a unique name.
