[releng][TSC] Decommision Nexus Log sever from Oct 1st, 2021.

Anil Belur

Hello all,

Presently, all of our CI job logs are shipped and stored on AWS S3 bucket [1.] and on Nexus2 Log server [2.]. We have been shipping/storing logs on the AWS S3 bucket, since this was enabled last year (Nov, 2020). Going forward the Nexus2 log server will be decommissioned and the Nexus2 server will exclusively host OpendayLight artifacts.  

Starting from October 1st, 2021 the Nexus logs server will be decommissioned, and ${LOG_SERVER} configuration on Jenkins will be re-configured to ship/store logs/files only on AWS S3 buckets, and any existing logs on the Nexus2 log server will be purged and the storage will be freed.

This requires the below change to be reviewed:
