Add ubuntu 20.04 support to skaled

[DmytroNazarenko]

• PRD: SYSTEM UPGRADE

According to adding compatibility of skale nodes with Ubuntu 20.04 we need to add Ubuntu 20.04 compatibility to skaled.

Need to check:

• Skaled has all needed changes to run on Ubuntu 20.04 machine
• Skaled still be compatible with 18.04 Ubuntu
