[202305][rsyslog]: Remote logging with the highest rule priority

[nazariig]

Why I did it

This fix resolves issue with missing certain types of messages while forwarding to the remote server.

Basically, this moves remote syslog forwarding rules to be executed before any other instructions take place,
so everything received by a local syslog instance will be forwarded to the remote machine.

The fix allows remote forwarding of messages defined as:
https://github.com/sonic-net/sonic-buildimage/blob/master/files/image_config/rsyslog/rsyslog.d/00-sonic.conf.j2

How I did it

• Moved rsyslog remote forwarding rules to be on top of other syslog instructions

How to verify it
