Add Spanner source and tool.
Spanner source is initialize with the following config:
```
sources:
my-spanner-source:
kind: spanner
project: my-project-name
instance: my-instance-name
database: my_db
# dialect: postgresql # The default dialect is google_standard_sql.
```
Spanner tool (with gsql dialect) is initialize with the following
config.
```
tools:
get_flight_by_id:
kind: spanner
source: my-cloud-sql-source
description: >
Use this tool to list all airports matching search criteria. Takes
at least one of country, city, name, or all and returns all matching
airports. The agent can decide to return the results directly to
the user.
statement: "SELECT * FROM flights WHERE id = @id"
parameters:
- name: id
type: int
description: 'id' represents the unique ID for each flight.
```
Spanner tool (with postgresql dialect) is initialize with the following
config.
```
tools:
get_flight_by_id:
kind: spanner
source: my-cloud-sql-source
description: >

at least one of country, city, name, or all and returns all matching
airports. The agent can decide to return the results directly to
the user.
statement: "SELECT * FROM flights WHERE id = $1"
parameters:
- name: id
type: int
description: 'id' represents the unique ID for each flight.
```
Note: the only difference in config for both dialects is the sql
statement.

Allow user to set if their database uses private or public ip. The
reason we add this is because the dialer require different
initialization with private and public ip.
By default, toolbox will use public ip.

Fixes a bug introduced in #43 where postgres-tool didn't think any of
the sources were valid.
The root cause of the bug was inconsistent usage of pointer/value in the
receiver functions. The fix updates everything to consistently use a
pointer receiver function.
This PR introduces the following breaking change: The
`alloydb-pg-generic`, `cloud-sql-pg-generic`, and
`postgres-generic-tool` have been replaced by the `postgres-sql` tool,
which works with all 3 Postgres sources.
If you were using of the the previous tools, you will need to update it
as follows:
```diff
example_tool:
- kind: cloud-sql-pg-generic
+ kind: postgres-sql
source: my-cloud-sql-pg-instance
description: some description
statement: |
SELECT * FROM SQL_STATEMENT;
parameters:
- name: country
type: string
description: some description
```
I'm proposing this change for the following reasons:
1. It provides greater flexibility between postgres-compatible sources
-- you can change between "postgres" and "alloydb-postgres" without
issue
2. The name "postgres-sql" is more clear that "postgres-generic" -- it
indicates it's a tool that runs SQL on the source
3. It's easier for us to maintain feature compatibility across a single
"postgres-sql" tool
Moves all of the "source" and "tool" implementations into their own
packages. This layout makes it a bit more clear where the
implementations are, and seems likely to scale more cleanly as more
sources and tools are added.
Adds support for "array" type parameters. Uses a subet of JSONSchema for
specification, in that arrays can be specified in the following way:
```yaml
parameters:
name: "my_array"
type: "array"
description: "some description"
items:
type: "integer"
```
Makes the following changes:
- Fills in previously stubbed "Invoke()" function for the Cloud SQL
Generic Tool
- Updates API to /{tool_name}/invoke to for invocation of said tool
- Updates response to use JSON
- Correctly returns error messages for invalid http codes
