Remove rsyslog plugin from all non eventd containers (#21338)

#### 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
