[PATCH 1/2] nvme-cli/fabrics: Add keep-alive-tmo param to connect cmd

[Steve Wise]

Added 'keep-alive-tmo' to 'connect' command so users can specify the
keep alive timeout period.

usage examples:

nvme connect --keep-alive-tmo=30 --transport=rdma --traddr=10.0.1.14 --nqn=test-nvme
nvme connect -k 30 -t rdma -a 10.0.1.14 -n test-nvme
