Rename external traffic flags

[NetanelBollag]

Deprecate the flags autoCreateNetworkPoliciesForExternalTraffic and autoCreateNetworkPoliciesForExternalTrafficDisableIntentsRequirement and replace them with the flag allowExternalTraffic who receives the options ifBlockedByOtterize, off or always.

Comparing the old flags to the allowExternalTraffic

allowExternalTraffic	autoCreateNetworkPoliciesForExternalTraffic	autoCreateNetworkPoliciesForExternalTrafficDisableIntentsRequirement
ifBlockedByOtterize	true	false
off	false	false
always	true	true
