Feat 56 run indexer

[helen-m-lin]

closes #56

• updated run.sh
• updated AindIndexBucketJobSettings.from_param_store to pull docdb job settings from aws secrets manager

At minimum, the parameter in aws parameter store should have:

{
  "doc_db_secret_name": "{docdb_secret_name}",
  "doc_db_db_name": "metadata_index",
  "doc_db_collection_name": "data_assets",
  "s3_buckets": [
    "{bucket1}",
    "{bucket2}",
    ...
  ]
}
