Adds logic to make the server shutdown gracefully, including better
respecting cancelled contexts and providing up to 10 seconds to finish
current connections.
1. Add []ParamAuthSource to every Parameter type implementation to
support authenticated configs. Create new constructors for types with
auth.
2. Tool invocation API changes to parse auth header and authentecated
parameters.
3. Add authSources to Tool manifest.
Logger might be created pre- or post- flag. The logger defined pre- and
post- flag should be using the same out and err writer.
This will ensure that the server uses the same out and err writer
defined with the `WithStreams` options.
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.
Logging support 4 different types of logging (debug, info, warn, error).
The default logging level is Info.
User will be able to set flag for log level (allowed values: "debug",
"info", "warn", "error"), example:
`go run . --log-level debug`
User will be able to set flag for logging format (allowed values:
"standard", "JSON"), example:
`go run . --logging-format json`

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`postgres-generic-tool` have been replaced by the `postgres-sql` tool,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.
1. Calculate tool manifests when server starts.
2. Add toolset manifest endpoints.

Add `Toolset` implementation to the `tools` package:
- struct and configs.
- Custom `UnmarshalYAML` function.
- Initialization function that validates if tools specified for the
toolset exist.
This PR adds preliminary parsing of parameters. Currently it only
supports 4 types: string, int, float32, and bool. Almost certainly we
will need to introduce more complicated parsing configuration (to handle
objects and arrays), but my initial attempts got quickly complicated, so
I simplified in the short term.
This also makes 2 breaking changes to config.yaml:
- changes "parameters" to be a list over object -- this is because
parameter ordering is important, and needs to be preserved
- removed the "required" field from parameter objects -- we need to
determine how to handle optional parameters in SQL queries
