Bug Description

Description
===========
Creating shares with Shared File Systems Option 1 (DHSS = False)
report errors

manila create NFS 1 --name share1
report errors
ERROR: There is no default share type available. You must pick a valid share type to create a share.
/etc/manila/manila.conf
Default has been defined in the configuration file_ share_ type = default_ share_ type

So I added a parameter to specify
manila create NFS 1 --name share1 --share-type default_ share_ type

Can create, but the result from the manila list is incorrect

check /var/log/manila/manila-scheduler.log

ERROR manila.scheduler.manager [None req-d198cf17-4892-42d3-9604-d4ba1daafe9e 0bbb72948a844ab5b44fd8ca513e76e8 f62ede92e97642 0d8f4b7cb9eab5a6b6 - - - -] Failed to schedule create_share: 'reserved_snapshot_percentage'

Hi,

I'm experiencing the same issue, it looks like the host manager is looking for an entry which doesn't exist:

Jun 05 12:54:25 ubuntu2204-devstack manila-scheduler[169298]: INFO manila.scheduler.host_manager [None req-9fa07831-1238-4787-97e1-e11883ce4210 admin None] CAPABILITY HAS: {'pool_name': 'Env8-SP-SW_SSD-1', 'thin_provisioning': True, 'total_capacity_gb': 4602, 'free_capacity_gb': 1485, 'allocated_capacity_gb': 67, 'provisioned_capacity_gb': 200, 'qos': False, 'reserved_percentage': 66, 'share_backend_name': 'powerflex', 'storage_protocol': 'NFS', 'vendor_name': 'Dell EMC', 'driver_version': '1.0', 'timestamp': datetime.datetime(2023, 6, 5, 12, 53, 28, 923517), 'driver_handles_share_servers': False, 'snapshot_support': True, 'create_share_from_snapshot_support': False, 'revert_to_snapshot_support': False, 'mount_snapshot_support': False, 'dedupe': False, 'compression': False, 'replication_type': None, 'replication_domain': None, 'sg_consistent_snapshot_support': None, 'security_service_update_support': False, 'network_allocation_update_support': False, 'share_server_multiple_subnet_support': False, 'ipv4_support': True, 'ipv6_support': False}

As you can see in the previous ouput, there is no reserved_snapshot_percentage Key.
