rails_helper.rb's only logic was to require
spec_helper.rb.

- After uninstalling the knative helm chart it's necessary to also
remove some leftover resources to allow the cluster to be clean
and knative to be reinstalleable.
- Adds knative uninstall disclaimer
- Uninstall ksvc before uninstalling knative

Make list of Knative and Ingres resources explicit

- To avoid deleting unwanted resources we are listing exact
which resources will be deleted rather than simply deleting any
resource that contains istio or knative words.

Remove Kn services cache from Clusters::Application::Knative

Knative function can exist even if user did not installed Knative via
GitLab managed apps.

-> Move responsibility of finding services into the Cluster
-> Responsability is inside Clusters::Cluster::KnativeServiceFinder
-> Projects::Serverless::FunctionsFinder now calls depends solely on a
cluster to find the Kn services.
-> Detect Knative by resource presence instead of service presence
-> Mock knative_installed response temporarily for frontend to develop

Display loader while `installed === 'checking'`

Added frontend work to determine if Knative is installed

Memoize with_reactive_cache(*args, &block) to avoid race conditions

When calling with_reactive_cache more than once, it's possible that the
second call will already have the value populated. Therefore, in cases
where we need the sequential calls to have consistent results, we'd fall
under a race condition.

Check knative installation via Knative resource presence

Only load pods if Knative is discovered

Always return a response in FunctionsController#index

- Always indicate if Knative is installed, not installed or checking
- Always indicate the partial response for functions. Final response is
guaranteed when knative_installed is either true | false.

Adds specs for Clusters::Cluster#knative_services_finder

Fix method name when calling on specs

Add an explicit check for functions

Added an explicit check to see if there are any functions available

Fix Serverless feature spec

- we don't find knative installation via database anymore,
rather via Knative resource

Display error message for request timeouts

Display an error message if the request times out

Adds feature specs for when functions exist

Remove a test purposed hardcoded flag

Add ability to partially load functions

Added the ability to partially load functions on the frontend

Add frontend unit tests

Added tests for the new frontend additions

Generate new translations

Generated new frontend translations

Address review comments

Cleaned up the frontend unit test.
Added computed prop for `isInstalled`.

Move string to constant

Simplify nil to array conversion

Put knative_installed states in a frozen hash for better read

Pluralize list of Knative states

Quey services and pods filtering name

This way we don't need to filter the namespace in memory.
Also, the data we get from the network is much smaller.

Simplify cache_key and fix bug

- Simplifies the cache_key by removing namespace duplicate
- Fixes a bug with reactive_cache memoization

Only prometheus can be uninstalled atm, the rest will be dealt with
later.

Presumption is that new application types will have uninstallation
implmemented at the same time.

- rewords examples starting with 'should'
- rewords examples starting with 'it'

Note: I had to manually fixup "onlies" to "only"

Adds `# frozen_string_literal: true` to spec/models ruby files

This is a gitlab-ee port of the following gitlab-ce MR:
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/25181

- Creates new route
- Creates new controller action
- Creates call stack:
  Clusterss::ApplciationsController calls -->
  Clusters::Applications::UpdateService calls -->
  Clusters::Applications::ScheduleUpdateService calls -->
  ClusterUpdateAppWorker calls -->
  Clusters::Applications::PatchService -->
  ClusterWaitForAppInstallationWorker

DRY req params

Adds gcp_cluster:cluster_update_app queue

Schedule_update_service is uneeded

Extract common logic to a parent class (UpdateService will need it)

Introduce new UpdateService

Fix rescue class namespace

Fix RuboCop offenses

Adds BaseService for create and update services

Remove request_handler code duplication

Fixes update command

Move update_command to ApplicationCore so all apps can use it

Adds tests for Knative update_command

Adds specs for PatchService

Raise error if update receives an unistalled app

Adds update_service spec

Fix RuboCop offense

Use subject in favor of go

Adds update endpoint specs for project namespace

Adds update endpoint specs for group namespace

- Adds to specs the case where apps are also updated
- Rename scope calls on Gitlab::UsageData and Clusters::Cluster
- Removes a duplicated spec

All applications except for Jupyter have the same #set_initial_status,
so create a new shared example which we include in all application specs
except for juptyer_spec. Juptyer specs already have specs for it's
version of #set_initial_status

This makes this consistent with :updated. And also avoids a potential
issue where an install errors which means that that the recorded version
won't necessarily reflect the version that is actually installed.
