Review how we install TDS Posgres

[cmoulliard]

To do

Review the existing bash script installing TDS Postgres Operator to use the tanzu client and not Helm anymore.
The steps will require to 👍🏻

• Relocate the TDS package
• Create and export a secret to access the private registry
• Install the Package repository
• Create a config file
• Deploy the operator using the TDS postgres package

Example

imgpkg copy -b registry.tanzu.vmware.com/packages-for-vmware-tanzu-data-services/tds-packages:1.0.2 --to-repo registry.harbor.10.0.77.176.nip.io:32443/tds/tds-packages
tanzu package repository add tanzu-data-services-repository --url registry.harbor.10.0.77.176.nip.io:32443/tds/tds-packages -n tap-install

tanzu secret registry add harbor-secret \
    --username <MY-REGISTRY-USERNAME> \
    --password <MY-REGISTRY-PASSWORD> \
    --server <MY-REGISTRY> \
    --export-to-all-namespaces --yes
