Multiple sstable* tools missing from the PATH of the official Docker image

[aldobongio]

All the up-to-date Cassandra Docker images are missing multiple sstable-related tools (for instance sstabledump):

#> docker run -d --name test cassandra:4.1.3
#> docker exec -it test ls /opt/cassandra/bin
cassandra  cassandra.in.sh  cqlsh  cqlsh.py  debug-cql  nodetool  sstableloader  sstablescrub  sstableupgrade  sstableutil  sstableverify  stop-server
#> docker stop test
#> docker rm -v test
#> docker run -d --name test cassandra:5.0-beta1
#> docker exec -it test ls /opt/cassandra/bin
cassandra  cassandra.in.sh  cqlsh  cqlsh.py  debug-cql  nodetool  sstableloader  sstablescrub  sstableupgrade  sstableutil  sstableverify  stop-server
#> docker stop test
#> docker rm -v test
docker run -d --name test cassandra:3.11.16
#> docker exec -it test ls /opt/cassandra/bin
cassandra         cassandra.in.sh  cqlsh.bat  debug-cql.bat  source-conf.ps1    sstablescrub      sstableupgrade.bat  sstableverify      stop-server.bat
cassandra.bat     cassandra.ps1    cqlsh.py   nodetool       sstableloader      sstablescrub.bat  sstableutil         sstableverify.bat  stop-server.ps1
cassandra.in.bat  cqlsh            debug-cql  nodetool.bat   sstableloader.bat  sstableupgrade    sstableutil.bat     stop-server

It looks like for some reason upstream chose to move those into tools/bin instead:

$ docker run --rm cassandra ls -l /opt/cassandra/tools/bin/

Good spot. How about adding /opt/cassandra/tools/bin/ to the PATH?

#> docker exec -it <CONTAINER_ID> nodetool version
ReleaseVersion: 3.11.16
#> docker exec -it <CONTAINER_ID> sstabledump
OCI runtime exec failed: exec failed: unable to start container process: exec: "sstabledump": executable file not found in $PATH: unknown

Interesting thought, but I do worry about how many of those are generally intended for use? For example, their Debian packages only put a few of them in PATH: https://github.com/apache/cassandra/blob/5321f88c40cc9ad280a7fb7472194b93e93334c0/debian/cassandra.install#L25-L30
