Enable build failure when code coverage is below threshold

[srnagar]

This PR includes two changes:

• Fails build if the code coverage drops below threshold
• Includes jacoco test coverage reporting steps in archetype-sdk-client.yml which were previously configured in client.yml

@JonathanGiles is this particular change going to require us to up the version and re-release the parent pom?

[srnagar]

@JimSuplizio since this change only introduces a check to fail the build when test coverage is low, it's not end user-facing. So, version update and re-release is not necessary.

Is it worth extracting these two minimum values out to properties so that child poms may overwrite this (in the future when we start setting a valid minimum and libraries need to opt-out for a valid reason)?

[srnagar]

Yes, updated this to use properties and also customized the threshold for a couple of storage modules that had really low coverage to:

• demonstrate how to customize the threshold per module
• increase the base threshold to a much higher number than 9%
