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.
Different databases require different types for `Params` field when
adding parameters to their statement. e.g. alloydb, cloudsql, and
postgres uses `pgxpool` to query and build sql statement, whereas
spanner uses `Spanner` library.
Added a new `ParamValue` struct. `ParseParams` helper function parses
arbitraryJSON object into `[]ParamValue`, and the tool's invoke will
convert `[]ParamValue` into it's required type.

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`postgres-generic-tool` have been replaced by the `postgres-sql` tool,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
