When using networking_routes with /32 CIDR, route will be removed and re added on every run.

Steps to reproduce:

• Set networking_routes to:

  networking_routes:
    - device: "eth2"
      network: "10.2.3.4/32"
      via: "172.23.0.1"

• Run playbok routes action 2 times.

actual result:

TASK [networking : remove not required routes] *********************************************************************************************************************************************

changed: [network01] => (item=10.2.3.4 via 172.23.0.1 dev eth2)

TASK [networking : add missing routes] *****************************************************************************************************************************************************
Friday 28 February 2020  12:35:14 +0100 (0:00:00.209)       0:00:26.750 ******* 
changed: [network01] => (item=10.2.3.4/32 via 172.23.0.1 dev eth2)

Possible solutions:

• Add note to readme about /32 cidr
• Find way to get ip routes including prefix length for /32 routes
