2.3 admin incompatibility with previous contracts

[OleksanderSalamatov]

During testing of Release 2.3 we found that if we have change IP function called before updating admin, after update we will have error in admin related to 'getLastChangeIpTime' was not found in this contract's abi. This was done before skale-manager contracts update to 1.10.0-beta.0. Skaled containers is not starting during this error.

Admin should have fallback mechanism to use old algorithm of dealing with change IP procedure.

Versions:
admin: 2.6.0-beta.0
skale-manager: 1.9.4-stable.0

Short log:

'getLastChangeIpTime' was not found in this contract's abi.", ' Are you sure you provided the correct contract abi?')
