#### Why I did it Fixes Issue #21227 - As of current, we have rsyslog_plugin and corresponding regex and configuration files in containers like bgp, swss, dhcp_relay. These binaries and files are built as part of the docker container itself. - This change removes that dependency by storing all rsyslog_plugin regex and conference files in the eventd docker container, and at runtime copying them to the host. - Fixes the issue that some images will not be able to publish certain events like "bgp-state", or "dhcp-relay-discard" due to reuse of docker containers during where eventd was disabled. #### How I did it - Removed all rsyslog plugin configuration and regex files from containers such as bgp, swss, dhcp_relay. All files for configuration and regexes are built inside eventd docker container. When eventd docker is started, it will copy these files to the host and restart rsyslog. - sshd regex and zebra regex are removed because those events are currently not being supported. - Possible race condition with rsyslog-config is avoided due to "After" and since rsyslog-config.service is type oneshot, rsyslog-config.sh is guaranteed to complete before eventd.service is called. #### How to verify it Tested on all elastic pipeline for 6 different HWSKUs Arista-7260CX, Arista720DT, Mellanox2700, Cisco 8102, Nokia M0, Arista 7060CX
