nvme-sysfs: add 'tls_configured_key' sysfs attribute
There is a difference between the negotiated TLS key (which is
always present for a TLS encrypted connection) and the configured
TLS key (which is specified with the --tls_key command line option).
To differentate between these two add a new sysfs attribute
'tls_configured_key' to hold the specified on the command line.
