Environment variable replacement is needed so that users don't have to
hardcode their secrets in configuring `tools.yaml`.
Both formats `$ENV_NAME` and `${ENV_NAME}` are standard ways to declare
an environment variable.
However, some database statement placeholders that are already using the
`$ENV_NAME` format.
Therefore, we only support env var declaration using `${ENV_NAME}` to
disambiguate it from other usages.

A Source represents a data sources that a tool can interact with. You can define
Sources as a map in the sources section of your tools.yaml file. Typically,
a source configuration will contain any information needed to connect with and
interact with the database.
{{< notice tip >}} Use environment variable replacement with the format ${ENV_NAME} instead of hardcoding your secrets into the configuration file. {{< /notice >}}
sources:
my-cloud-sql-source:
kind: cloud-sql-postgres
project: my-project-id
region: us-central1
instance: my-instance-name
database: my_db
user: ${USER_NAME}
password: ${PASSWORD}
In implementation, each source is a different connection pool or client that used to connect to the database and execute the tool.
