IMPALA-9008: Serialize Maven invocations to deflake impala-minimal-hive-exec
Building impala-minimal-hive-exec was flaky (sometimes it failed
to download Guava 14.0.1), and my guess is that it is related to
downloading the same dependency in parallel with ext-data-source.
Similarly to the solution in IMPALA-7051, I try to fix it by
adding a fictional dependency (ext-data-source -> shaded-deps)
to serialize the build.
Full Maven dependency graph:
fe -> yarn-extras -> ext-data-source -> shaded-deps -> impala-parent
The ordering of yarn-extras, ext-data-source, and shaded-deps are
arbitrary.
Testing:
- I never reproduced the original flakiness, so I just hope
that it disappears with this change.

> Building impala-minimal-hive-exec fails time to time while downloading one of
> it's dependencies (Guava 14.0.1). In the mvn logs of failed builds
> impala-minimal-hive-exec and ext-data-source were running in parallel, and
> latter also downloads Guava 14.0.1. This lead me to assume that this is a
> similar issue to IMPALA-7051.
