Make Liveness and Readiness Probes

[dan-fernandes]

Currently glazed does not have liveness or readiness probes configured.

Acceptance Criteria:

1. Glazed serves and endpoint to indicate readiness
2. Glazed serves an endpoint to indicate liveness
3. Glazed's deployment is configured to check these for liveness and readiness

Do these have to be different? Is there any state where glazed is alive but not ready?
