Vespa Cloud deploy does not consider custom instance

[ldalves]

Using vespa-cli I can set a custom instance like:

vespa config set application vespa-team.text-search.leandro

Using pyvespa I don't have an option to pass the instance name in VespaCloud, but instead I have to pass it in the vespa_cloud.deploy.

vespa_cloud = VespaCloud(
    tenant=tenant,
    application=application,
    application_package=app_package,
)

vespa_cloud.deploy(instance=instance)

The instance above is set to leandro, but in the logs we can see that it is set to default:

Setting application...
Running: vespa config set application vespa-team.text-image-search
Setting target cloud...
Running: vespa config set target cloud

No api-key found for control plane access. Using access token.

Certificate and key not found in /Users/leandro/dev/ldalves/text-image-search/.vespa or /Users/leandro/.vespa/vespa-team.text-image-search.default: Creating new cert/key pair with vespa CLI.

Success: Private key written to '/Users/leandro/.vespa/vespa-team.text-image-search.default/data-plane-private-key.pem'

In order to fix this, we need to allow passing instance to VespaCloud as well and set it in the vespacli if not default.
