* feat: Support getOrNull and getOrDefault in Struct

* Addressed comments

* Change Function interface to BiFunction

* Update clirr ignored differences

SET statements that set a duration, e.g. max_commit_delay or statement_timeout,
did not allow setting a zero duration. This is however sometimes useful, as the
server default for max_commit_delay is not zero. This means that setting this to
zero triggers a different behavior than not setting a value, as when no value is
included in a commit request, Spanner will choose a reasonable value for the
commit delay. By explicitly setting it to zero, Spanner will always also use a
zero commit delay.

* Update SpannerSample.java

Encapsulates both statements in a try-with-resources statement

* Update SpannerSample.java

* Update SpannerSample.java

Fix spacing linter errors

* Update SpannerSample.java
