progagate uri query string to lance; add aws integration tests (#486)

# WARNING: specifying engine is NOT a publicly supported feature in
lancedb yet. THE API WILL CHANGE.

This PR exposes dynamodb based commit to `vectordb` and JS SDK (will do
python in another PR since it's on a different release track)

This PR also added aws integration test using `localstack`

## What?
This PR adds uri parameters to DB connection string. User may specify
`engine` in the connection string to let LanceDB know that the user
wants to use an external store when reading and writing a table. User
may also pass any parameters required by the commitStore in the
connection string, these parameters will be propagated to lance.

e.g.
```
vectordb.connect("s3://my-db-bucket?engine=ddb&ddbTableName=my-commit-table")
```
will automatically convert table path to
```
s3+ddb://my-db-bucket/my_table.lance?&ddbTableName=my-commit-table
```
