Bump com.google.guava:guava from 31.1-jre to 32.1.2-jre

[cplohitha]

This PR is raised for upgrading com.google.guava:guava from 31.1-jre to 32.1.2-jre. Previously the guava version was picked from com.google.cloud libraries-bom version 26.1.1

<groupId>com.google.cloud</groupId> <artifactId>libraries-bom</artifactId> <version>26.1.1</version>

Now overrode to picking the version from plugin POM as there were other version updates in the latest versions of the google cloud bom.
