Add separate api fields for load balancing specification

[HiranmoyChowdhury]

there is no way of getting weight other than this. and this requires only because of read replica in postgres(one may not have the same resource as others do)

sync -> backends ?

type PgpoolCustomConfigurationSpec struct {
*ReconfigurationSpec json:",inline,omitempty"
Backends []v1alpha2.PgpoolLoadBalancingSpec json:"backends,omitempty"
}

basically like this?

spec:
  configuration:
     backends:
     - hostName: demo.xyz
       weight: 1
       port: 5432
    delete:
      - reporting
      - analytics

not getting sync -> backends

[ArnobKumarSaha]

basically like this?

spec:
  configuration:
     backends:
     - hostName: demo.xyz
       weight: 1
       port: 5432
    delete:
      - reporting
      - analytics

right.

[HiranmoyChowdhury]

just wanna confirm if you want this...
so, this will be like:

spec:
  configuration:
    backends:
    - hostName: demo.xyz
      weight: 1
      port: 5432
    delete:
      - reporting
      - analytics
    configSecret:
      name: secretName
    removeCustomConfig: true

just thought, configuration.delete is a bit unclear...

currently we are doing it like:

spec:
  configuration:
    backend:
      sync:
        - name: demo
          weight: 2
        - name: demo2
          weight: 10
        - name: STANDBY
          weight: 8
      delete:
        - PRIMARY
    removeCustomConfig: true
    configSecret:
      name: pp-custom-config
    applyConfig:
      pgpool.conf: |-
        max_pool = 72
        num_init_children = 9

maybe delete -> deleteBackends: ?? @ArnobKumarSaha

[ArnobKumarSaha]

basically like this?

spec:
  configuration:
     backends:
     - hostName: demo.xyz
       weight: 1
       port: 5432
    delete:
      - reporting
      - analytics

right.
