#145 - Register HealthCheckRegistry

[reshmabidikar]

Work for #145.

Edit: 2025-05-28: I did some more investigations and I think the system works as expected. See this comment.

I've tested this from the hello-world-plugin. See this PR. So, I can access KB healthcheck and plugins healthcheck from the hello-world-plugin. However, I'm unable to check the health of an individual plugin like Aviate. (See this line).

So a few questions:

• Do the changes in this PR look good?
• Is the testing approach correct?
• Should we be able to access healthcheck for an individual plugin like Aviate like done here?

This is what I see:

[main.pool.ConnectivityCheck, org.killbill.billing.server.healthchecks.KillbillHealthcheck, org.killbill.billing.server.healthchecks.KillbillPluginsHealthcheck, org.killbill.billing.server.healthchecks.KillbillQueuesHealthcheck, osgi.pool.ConnectivityCheck, shiro.pool.ConnectivityCheck]

Don't we need to also make this service available from the KillbillActivatorBase - if not do we expect, plugins to use ServiceTracker apis to fetch the OCGI bundle?

Made changes in the code to make the HealthCheckRegistry available in KillBillActivatorBase. See 92e334d. Verified that the HealthCheckRegistry is available via KillBillActivatorBase in the hello-world-plugin. See this commit.
