Add TLS configuration

[jnugh]

As described in #917 there is currently no way to specify parameters for the TLS connections which is required if one would like to (in our case) use a TLS client certificate or maybe even disable certificate checks altogether as in #694).

I'm not sure if the approach on how to supply configuration parameters is a good one (I just added a configuration struct using manage that can be changed from other parts of the application).

Let me know if any documentation should be done as well :)

Closes #917. Closes #694

Thanks for contributing and sorry for the delay :)

I think it'd be better to just refactor plugin init to a builder similar to

plugins-workspace/plugins/sql/src/plugin.rs

Lines 270 to 287 in 7cefa2b

	#[derive(Default)]
	pub struct Builder {
	migrations: Option<HashMap<String, MigrationList>>,
	}
	impl Builder {
	pub fn new() -> Self {
	Self::default()
	}
	/// Add migrations to a database.
	#[must_use]
	pub fn add_migrations(mut self, db_url: &str, migrations: Vec<Migration>) -> Self {
	self.migrations
	.get_or_insert(Default::default())
	.insert(db_url.to_string(), MigrationList(migrations));
	self
	}

(careful, that's v2 but the syntax should be the same in v1)

I completely forgot that there was a todo in this PR. Thank you very much for updating and merging the change 🙏🏽
