Increase Ironic inspector dnsmasq lease time

Browse Source 
As described in bug, its possible that addresses provided to IPA via
DHCP may expire and not be added to the introspection report.  This
increases the dhcp lease time from 2 to 10 minutes.  There should be
no downside to increasing this lease time since these addresses
are only used during introspection.

fixes:
- Increase the Inspector DHCP lease time that is provide by dnsmasq to 10
minutes. A shorter lease time may cause the provided IP address to expire
and IPA may not add the address to the introspection report.
