Adds improved default auth to Milvus

[timheuer]

• Updates Milvus hosting to leverage dynamically generated default password if none provided (similar to other resources) and resulting cascading changes + tests.
• Updates tags for contianer image that support setting auth

Description

Milvus added the ability to set the root password. This change adapts to that and follows similar pattern to other config-based auth (e.g., MySql is a good analog). This requires the support of a minimum new Milvus version (2.4.7).

Fixes #4966

@eerhardt had to redo the PR (my branch was way stale). Addressed your prior feedback.

Review: this does change resource and enables a null param were there wasn't before. Not sure if we've made a similiar change there -- seeking feedback on desired correct way here.

I believe you did it correctly. 👍

Would this allow adding Milvus playground app to the tests like in #5244 ? When I had tried it earlier on main it was failing with Parameter resource could not be used because configuration key 'Parameters:milvusauth' is missing and the Parameter has no default value..

Yes, it should.

When I had tried it earlier on main it was failing with Parameter resource could not be used because configuration key 'Parameters:milvusauth' is missing and the Parameter has no default value..

I thought we generated random parameter values:

aspire/tests/Aspire.Playground.Tests/Infrastructure/DistributedApplicationExtensions.cs

Lines 25 to 34 in 89f5fb6

	public static TBuilder WithRandomParameterValues<TBuilder>(this TBuilder builder)
	where TBuilder : IDistributedApplicationTestingBuilder
	{
	var parameters = builder.Resources.OfType<ParameterResource>().Where(p => !p.IsConnectionString).ToList();
	foreach (var parameter in parameters)
	{
	builder.Configuration[$"Parameters:{parameter.Name}"] = parameter.Secret
	? PasswordGenerator.Generate(16, true, true, true, false, 1, 1, 1, 0)
	: Convert.ToHexString(RandomNumberGenerator.GetBytes(4));
	}

Isn't that code supposed to fix this error?

Any other feedback @eerhardt?

This looks good to me. Nice work! Much easier to get started with Milvus.
