Deploy some SLC dependencies in own S3 Bucket

[tomuben]

Background

SLC have tons of dependencies, from different sources (Ubuntu, CRAN, PyPi, GCloud(Swig), Docker, Github , Exasol Website).
Many times one of those sources has connection issues, and hence the Nightly/CI build break.
We could try to host some small, stable artifacts on S3, and pull them during the build from there. Currently this is already done for SWIG. Also, some Exasol specific artificats could be hosted there (Check https://console.cloud.google.com/cloud-build/builds;region=global/fcae648f-da77-4ec6-bee3-a8ddf0a77312?project=script-languages-build)

Acceptance Criteria

1. Create a public bucket on S3 (public readonly access)
2. Deploy specific artifacts there:

• Exasol ODBC driver
• SWIG

3. Change path in Dockerfiles to pull artifacts from there

Note: Exasol JDBC Driver will be moved to Maven Central, and can be fetched from there.
