Add stx-fm-trap-subagent docker image

This change reorganizes the source directories of the stx-fm-subagent
container to be reused by both CentOS and Debian Dockerfiles in order
to build the images having the corresponding OS-specic base.

Test plan:

PASS: Debian - Build Debian docker image and upload/apply snmp-app
changing the stx-fm-trap-subagent references to point to the new image.
Verified that the app is applied, and the container is created.
PASS: Verified common snmp scenarios:
 - test snmpwalk for 2c and 3 snmp version
 - test snmpget for 2c and 3 snmp version
 - verified traps are working as expected.

PASS: CentOS - Same tests have been done building a CentOS container.
