Changpeng Liu 3b673b8431 nvmf/vfio_user: disable vfio_user by default 
Users can use "--with-vfio-user" to enable it when testing it.
For CI configuration, we add a new test flag SPDK_TEST_VFIOUSER
to enable CI tests.

WARNING: The Infiniband Verbs opcode Send With Invalidate is either not

Beginning with Linux kernel 4.14, the kernel NVMe-oF initiator leverages Send
With Invalidate RDMA operations to improve performance. Failing to use the
Send With Invalidate operation on the NVMe-oF target side results in full
functionality, but greatly reduced performance. The SPDK NVMe-oF target will
be unable to leverage that operation using the currently installed version
of libibverbs, so Linux kernel NVMe-oF initiators based on kernels greater
than or equal to 4.14 will see significantly reduced performance.
