We want to tell the user what went wrong while fetching the config.
Thus this patch shows the error in the UI if there is any while config
fetch.

If there is some error while processing the kubeconfig we want to pass
that error to the frontend so that we can communicate the error.

We were fetching clusters every time the cluster length is 0 which
shouldn't be the case because when there is no cluster config available
because of some error at processing the kubeconfig we don't want to keep
on fetching.

We were using log.Fatal whenever there is no config present and as
log.Fatal internally gives a call to os.exit and because of which our
server stops. We don't want this behaviour and whenever there is no
config present we just want to log that info without stopping the
server.

The react-scripts package had severe vulnerability, and the new version
needs a new eslint.

The instructions for the Ingress referred to a missing YAML file, so
this patch adds the file and updates the docs.

Add new README and docs

Store sidebar shrink status to localStorage

We want to store sidebar shrink status to localStorage so that we
persist the sidebar status even after the browser is closed.

Add Sort to table columns

For every used instance of SimpleTable we want to add the sort functions
to be passed with the columns wherever it is required.

Adds Shrink Sidebar according to the new design and also navigation tabs

AppBar and app logo on the sidebar are not aligned properly. This patch
reduces the padding amount to the logo in order to align logo and appbar
in one line.

When we change the theme the sidebar state was getting set to the shrink
mode which should not be the case. The fix to this is very simple we
just need to use the shrink state default value from redux store.

As the sidebar is shrinked we have more space on the toolbar and we
want to always show the chooser in the center of the toolbar.

This patch removes the fixed drawerWidth padding to chooser and adjusts
it based on whether the sidebar is open or not.

When in sidebar shrink mode we want to show the version and icon one
above the other and not as flex display.

We want to show a tooltip to sidebar icons when they are shrink mode to
provide more readability to user and to achieve a better UX.

NavigationTabs component is needed to render sublist of a sidebar
main property whenever we are in the sidebar shrink mode. Thus this
patch creates the component and also uses it in the app.

We need two actions for sidebar shrink status and whether the sidebar
icon is clicked, Also we need to update the reducers accordingly.

Thus this patch adds two more properties to ui sidebar state about
sidebar shrink status and whether the sidebar icon is clicked and also
adds the relevant actions for them.

We need to use Tabs component when the sidebar is in shrink mode. This
also means we need to configure our Tabs component such that it can
take in default Values from outside and also reset to default whenever
asked for which should also be controlled from outside via prop.

We want to add sort icons to each table column header which passes the
sort function with it while the SimpleTable component is rendered. This
patch adds the sort functionality to the SimpleTable component.

frontend: Show plugins' header actions before others

We were showing the plugins' header actions after the default ones but
this means that the UI is less consistent among views, e.g.: if a plugin
added a header button in pods' details but not in the deployments', then
the other buttons would be pushed left. This was even more evident if
the plugin took a while to add the button (even leading to a misclick).

This patch makes the plugins' header action components be added to the
left, so the rest of the buttons don't move in such case.

We need the headlamp logo without text when the sidebar is shrinked.
Thus this patch adds the new logo to resources which will be used when
the sidebar is shrinked.

As we want to add the shrinkable sidebar. We need to change the styles
of the sidebar to allow collapse.

Add Dark Theme

As we change from light to dark theme we want to use black icon and text
color for light theme and white color for dark theme. This patch adds
the color and uses it in chooser icons and texts.

For dark theme we use a little lighter background for showing different
statuses. Thus this patch updates the success,error,warning colors for
dark mode.

For dark theme we want to use a different set of colors than what we use
for light theme for charts,resources and tooltips.

This patch adds these colors to the theme and uses them.

We want to use the theme when setting styles for the AppBar but right
now we were using useStyles outside the ThemeProvider which was leading
to use the default theme configs to be used in AppBar and not the one
we want to set.

This patch refactors the App component and segregates the entire App in
a seperate AppContainer component which receives the current theme to be
used via ThemeProvider.

We want to switch between dark and light themes with a click of button.

Thus this patch configures the app to have the button on the top bar for
theme change and also configure theme settings for light and dark theme.
