Merged PR 1291: Fix rsyslog issue in master pipeline

In PR: https://dev.azure.com/mssonic/internal/_git/sonic-mgmt-int/pullrequest/1151,  we patched rsyslog to send out rsyslog message to lab server and ingests to Kusto. With the SONiC version information, we can query syslog of lab DUTs in Kusto by its version information.

However, master image has added template="SONiCFileFormat" in PR: sonic-net/sonic-buildimage#10991, which caused issue: https://msazure.visualstudio.com/One/_workitems/edit/15990217

To solve this issue, in master image pipeline, we replace template=.*SONiCFileFormat with template=RemoteSONiCFileFormat; in internal image pipeline, we add template=RemoteSONiCFileFormat to action omfwd
