[PATCH 2/2] nvme-cli/fabrics: Add reconnect-delay param to connect cmd

[Steve Wise]

Added 'reconnect-delay' to 'connect' command so users can specify the
delay time, in seconds, before reconnecting due to a keep alive timeout.

usage examples:

nvme connect --reconnect-delay=30 --transport=rdma --traddr=10.0.1.14 --nqn=test-nvme
nvme connect -r 30 -t rdma -a 10.0.1.14 -n test-nvme
