 56b49dcee8 Ability to retain specialised pods for poolmanager functions (#2830) 
- added retainPods flag to take in the number of specialized pods to retain
- add retainPods in both the create function and update function command
- modify crd keys to be typed instead of string
- keep track of function generation in case of update function operation
- add delete handler function to make sure specialized pods are deleted in case function is deleted

maxSkew:
description: 'MaxSkew describes the degree to which pods
may be unevenly distributed. When `whenUnsatisfiable=DoNotSchedule`,
it is the maximum permitted difference between the number
of matching pods in the target topology and the global
minimum. The global minimum is the minimum number of matching
pods in an eligible domain or zero if the number of eligible
domains is less than MinDomains. For example, in a 3-zone
cluster, MaxSkew is set to 1, and pods with the same labelSelector
spread as 2/2/1: In this case, the global minimum is 1.
| zone1 | zone2 | zone3 | | P P | P P | P | -
if MaxSkew is 1, incoming pod can only be scheduled to
zone3 to become 2/2/2; scheduling it onto zone1(zone2)
would make the ActualSkew(3-1) on zone1(zone2) violate
MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled
onto any zone. When `whenUnsatisfiable=ScheduleAnyway`,
it is used to give higher precedence to topologies that

minDomains:
description: "MinDomains indicates a minimum number of eligible
domains. When the number of eligible domains with matching
topology keys is less than minDomains, Pod Topology Spread
treats \"global minimum\" as 0, and then the calculation
of Skew is performed. And when the number of eligible
domains with matching topology keys equals or greater
than minDomains, this value has no effect on scheduling.
As a result, when the number of eligible domains is less
than minDomains, scheduler won't schedule more than maxSkew
Pods to those domains. If value is nil, the constraint
behaves as if MinDomains is equal to 1. Valid values are
integers greater than 0. When value is not nil, WhenUnsatisfiable
must be DoNotSchedule. \n For example, in a 3-zone cluster,
MaxSkew is set to 2, MinDomains is set to 5 and pods with
the same labelSelector spread as 2/2/2: | zone1 | zone2
| zone3 | | P P | P P | P P | The number of domains
is less than 5(MinDomains), so \"global minimum\" is treated
as 0. In this situation, new pod with the same labelSelector
cannot be scheduled, because computed skew will be 3(3
- 0) if new Pod is scheduled to any of the three zones,
it will violate MaxSkew. \n This is a beta field and requires

instance of a topology. Also, we define an eligible domain
as a domain whose nodes meet the requirements of nodeAffinityPolicy
and nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname",
each Node is a domain of that topology. And, if TopologyKey
is "topology.kubernetes.io/zone", each zone is a domain
of that topology. It's a required field.

whenUnsatisfiable:
description: 'WhenUnsatisfiable indicates how to deal with
a pod if it doesn''t satisfy the spread constraint. -
DoNotSchedule (default) tells the scheduler not to schedule
it. - ScheduleAnyway tells the scheduler to schedule the
pod in any location, but giving higher precedence to topologies
that would help reduce the skew. A constraint is considered
"Unsatisfiable" for an incoming pod if and only if every
possible node assignment for that pod would violate "MaxSkew"
on some topology. For example, in a 3-zone cluster, MaxSkew
is set to 1, and pods with the same labelSelector spread
as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P |
If WhenUnsatisfiable is set to DoNotSchedule, incoming
pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2)
as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1).
In other words, the cluster can still be imbalanced, but
