You can have "bond-miimon 100" in "/etc/network/interfaces" rather
than "options bonding mode=1 miimon=100" in
"/etc/modprobe.d/bonding.conf".

Why do you have "alias netdev-bond1 bonding" in
"/etc/modprobe.d/bonding.conf" rather than "alias bond1 bonding"?

You need "options bonding max_bonds=2" in
"/etc/modprobe.d/bonding.conf" because it defaults to "1".
