Climate card change - Add target temperature

[kelaban]

Description

Add target temperature to climate-card

• Introduces show_target_temperature configuration param for climate-card
• Adds climate-view to showcase for development

Related Issue

This PR closes issue: fixes #636

Motivation and Context

The default (hass native) climate entity card shows both the target temperature and the current temperature. This change adds the target temperature to mushroom climate-card to be displayed when the climate device is turned on and the required configuration is set.

To gate the change and prevent dashboards from automatically changing their appearance a new configuration parameter is introduced called show_target_temperature which defaults to false.

HASS Entity Card Climate Appearance

Mushroom show_target_temperature: false

Mushroom show_target_temperature: true

New Showcase View

How Has This Been Tested
