Service Warm-up Time Monitoring

Hi all,

Backend-infra team has updated the dependency at old-monorepo to be able to monitor the warm-up time for each application service. But we only updated the code at a few classes, so we need your help to do it for other services. How to wire it:

updating the dependency to application-jetty and application-base (already done for old-monorepo repository but not at other repositories)

for application-jetty v2, use version >= 2.6.0
for application-jetty v3, use version >= 3.7.0
for application-base, use version >= 1.4.0

set observer at the contructor of the service component

You can see the example of how to do it in the code review https://phabricator.noc.tvlk.cloud/differential/revision/edit/83202/.

The metrics will appear in Datadog as warmup.elapsedTime and will have > 2 additional tags:

appgroup: service name
success: true/false
exception: the exception class name, only available if there is an exception when starting the service

Thank you!
