fabtests/examples: Add libfabric examples

Add examples to explain basic libfabric apis. Four examples
are added:

example_rdm.c:
Explain simple message exchange between server and client
using RDM endpoint.

example_rdm_oob.c:
This example explains simple meesage exchange with out of band
addressing capability.

example_rdm_rma.c:
Explain message exchange using remote memory access. Two
operations are explained here, remote write and remote read.
In local write operation, client is going to write data from
its local write buffer to the servers write buffer. In
remote read operation, the server is going to read data from
client’s read buffer into its own local read buffer.

example_rdm_tagged.c:
This example demonstrates how tagged messages work and
specifically how the messages are received in the same order
as they were sent.
