Storing CF API token data in domain config

[yura3d]

Fixes #2398

This PR changes the storage location of Cloudflare's API Token, Account ID and Zone ID from account config to domain config.

For now, to save these vars to domain config we need to set Zone ID, otherwise the vars will be stored to account (global) config:

acme.sh/dnsapi/dns_cf.sh

Lines 28 to 37 in aa8cf76

	if [ "$CF_Zone_ID" ]; then
	_savedomainconf CF_Token "$CF_Token"
	_savedomainconf CF_Account_ID "$CF_Account_ID"
	_savedomainconf CF_Zone_ID "$CF_Zone_ID"
	else
	_saveaccountconf_mutable CF_Token "$CF_Token"
	_saveaccountconf_mutable CF_Account_ID "$CF_Account_ID"
	_clearaccountconf_mutable CF_Zone_ID
	_clearaccountconf CF_Zone_ID
	fi

This makes it impossible to handle miltiple zones (using Account ID instead of Zone ID) from multiple Cloudflare accounts on the same server: we can't have different values of API Token and Account ID in account config.
