Move creation of temporary directory to Java (#36002)
In the long run we want to move all of startup to a Java program. This
will simplify our startup scripts and make maintenance of startup less
dependent on the underlying platform that we run on. This commit moves
the creation of the temporary directory off of system-dependent commands
and onto a simple Java program.

Choose JVM options ergonomically
With this commit we add the possibility to define further JVM options (and
system properties) based on the current environment. As a proof of concept, it
chooses Netty's allocator ergonomically based on the maximum defined heap size.
We switch to the unpooled allocator at 1GB heap size (value determined
experimentally, see #30684 for more details). We are also explicit about the
choice of the allocator in either case.

Ryan Ernst bd5c1a4590 Move java version checker back to its own jar (#30708)
The java version checker requires being written with java 7 APIs.
In order to use java 8 apis in other launcher utilities, this commit
moves the java version checker back to its own jar.

   Elasticsearch
 - move JVM options to its own page of the docs
 - move configuring the heap to important Elasticsearch settings
 - move configuring the heap to its own page of the docs
 - move all important settings to individual pages in the docs
 - remove bootstrap.memory_lock from important settings, this is covered
   in the swap section of system configuration

Extend JVM options to support multiple versions
JDK 9 has removed JVM options that were valid in JDK 8 (e.g., GC logging
flags) and replaced them with new flags that are not available in JDK
8. This means that a single JVM options file can no longer apply to JDK
8 and JDK 9, complicating development, complicating our packaging story,
and complicating operations. This commit extends the JVM options syntax
to specify the range of versions the option applies to. If the running
JVM matches the range of versions, the flag will be used to start the
JVM otherwise the flag will be ignored.

We implement this parser in Java for simplicity, and with this we start
our first step towards a Java launcher.
