designate charm should allow infoblox settings

[Patrizio Bassi]

as Infoblox driver is now part of Designate component out-of-the-box the designate charm should allow the infoblox configuration. https://docs.openstack.org/designate/latest/contributor/backends/infoblox.html

It could be feasable to have a "dns-slaves" - like option with all needed params

[Patrizio Bassi (patrizio-bassi)]

needed params:

wapi_url
username
password
sslverify default=false
multi_tenant default=False
http_pool_connections default=100
http_pool_maxsize default=100
dns_view default='default'
network_view default='default'

I gave it a try implementing this, could anyone please take a look at https://review.opendev.org/c/openstack/charm-designate/+/762157 ?
