AggregateTypeAffinityFilter cannot filter on multiple instance_type values

[sean mooney]

AggregateTypeAffinityFilter limits instance_type by aggregate

At present it is not possible to specify multiple instance_types for an Aggregate with this filter.

This prevent operators form creating a single host aggregate for a group of related flavors.
For example a host aggregate for all flavors that support hugepages or a host aggregate for all flavors that support
ssds.

Without this functionality the operator would have to create one host aggregate per flavor/instance_type and add the same host to multiple aggregates.

    Add AggregateTypeAffinityFilter multi values support

    This change allows the AggregateTypeAffinityFilter to function when
    multiple instance_type names are set in the Aggregate Metadata.
    This change implements and documents a new comma separated syntax for
    the aggregate instance_type metadata attribute. The legacy syntax is
    still supported when a single instace_type is specified.
    e.g. 'm1.nano' or "m1.nano,m1.small"
