3b0705ba63 IMPALA-11941: Support Java 17 in Impala
Enables building for Java 17 - and particularly using Java 17 in
containers - but won't run a minicluster fully with Java 17 as some
projects (Hadoop) don't yet support it.

Starting with Java 15, ehcache.sizeof encounters
UnsupportedOperationException: can't get field offset on a hidden class
in class members pointing to capturing lambda functions. Java 17 also
introduces new modules that need to be added to add-opens. Both of these
pose problems for continued use of ehcache.

Adds https://github.com/jbellis/jamm as a new cache weigher for Java
15+. We build from HEAD as an external project until Java 17 support is
released (https://github.com/jbellis/jamm/issues/44). Adds the
'java_weigher' option to select 'sizeof' or 'jamm'; defaults to 'auto',
which uses jamm for Java 15+ and sizeof for everything else. Also adds
metrics for viewing cache weight results.

Adds JAVA_HOME/lib/server to LD_LIBRARY_PATH in run-jvm-binary to
simplify switching between JDK versions for testing. You can now
- export IMPALA_JDK_VERSION=11
- source bin/impala-config.sh
- start-impala-cluster.py
and have Impala running a different JDK (11) version.

Retains add-opens calls that are still necessary due to dependencies'
use of lambdas for jamm, and all others for ehcache. Add-opens are still
required as a fallback, as noted in
https://github.com/jbellis/jamm#object-graph-crawling. We catch the
exceptions jamm and ehcache throw - CannotAccessFieldException,
UnsupportedOperationException - to avoid crashing Impala, and add it to
the list of banned log messages (as we should add-opens when we find
them).

Testing:
- container test run with Java 11 and 17 (excludes custom cluster)
- manual custom_cluster/test_local_catalog.py +
  test_banned_log_messages.py run with Java 11 and 17 (Java 8 build)
- full Java 11 build (passed except IMPALA-12184)
- add test catalog cache entry size metrics fit reasonable bounds
- add unit test for utility to find jamm jar file in classpath

56ee90c598 IMPALA-9760: Add IMPALA_TOOLCHAIN_PACKAGES_HOME to prepare for GCC7
The locations for native-toolchain packages in IMPALA_TOOLCHAIN
currently do not include the compiler version. This means that
the toolchain can't distinguish between native-toolchain packages
built with gcc 4.9.2 versus gcc 7.5.0. The collisions can cause
issues when switching back and forth between branches.

This introduces the IMPALA_TOOLCHAIN_PACKAGES_HOME environment
variable, which is a location inside IMPALA_TOOLCHAIN that would
hold native-toolchain packages. Currently, it is set to the same
as IMPALA_TOOLCHAIN, so there is no difference in behavior.
This lays the groundwork to add the compiler version to this
path when switching to GCC7.

Testing:
 - The only impediment to building with
   IMPALA_TOOLCHAIN_PACKAGES_HOME=$IMPALA_TOOLCHAIN/test is
   Impala-lzo. With a custom Impala-lzo, compilation succeeds.
   Either Impala-lzo will be fixed or it will be removed.
 - Core tests

c43c03c5ee IMPALA-3926: part 2: avoid setting LD_LIBRARY_PATH
This removes LD_LIBRARY_PATH and LD_PRELOAD from the
developer's shell and cleans it up. With the preceding
change, toolchain utilities like clang can be run without
a special LD_LIBRARY_PATH.

This fixes a bug where libjvm.so was registered as a
static instead of a shared library, which adds it to the
RUNPATH variable in the binary, which provides a default
search location that can be overriden by LD_LIBRARY_PATH.

Impala binaries don't have the rpath baked in for some
libraries, including Impala-lzo, libgcc and libstdc++.
, so we still need to set LD_LIBRARY_PATH when running
those. That is solved with wrapper scripts that sets
the environment variables only when invoking those
binaries, e.g. starting a daemon or running a backend
test. I added three scripts because there were 3 sets
of environment variables. The scripts are:
* run-binary.sh: just sets LD_LIBRARY_PATH
* run-jvm-binary.sh: sets LD_LIBRARY_PATH and CLASSPATH
* start-daemon.sh: sets LD_LIBRARY_PATH and CLASSPATH and
  kerberos-related environment variables.

The binaries, in almost all cases, work fine without
those tweaks, because libstdc++ and libgcc are picked
up along with libkuduclient.so from the toolchain (they
are in the same directory). I decided to leave good enough
alone here. run-binary.sh and friends can be used in
any remaining edge cases to run binaries.

An alternative to the 3 scripts would be to have an
uber-script that set all the variables, but I felt
that it was better to be specific about what
each binary needed. Cleaning the LD_LIBRARY_PATH
mess up has given me a distaste for scattershot
setting of environment variables. I am open to
revisiting this.

Testing:
* Ran tests on centos 7
* Manually tested that my dev env with
 LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu continued
 to work (for now). All ubuntu 16.04 and 18.04 dev
 envs that were set up with bootstrap_development.sh
 will be in this state.
