remove special case publishing of extension point implementation metadata: dx/excshell/1

[shazron]

With the release of the Template Registry API integration, we still have this special-case for the dx/excshell/1 extension that could not be resolved:

aio-cli-plugin-app/src/commands/app/deploy.js

Lines 250 to 253 in 35dd448

	if (payload.endpoints['dx/excshell/1'] && payload.endpoints['dx/excshell/1'].view) {
	const metadata = await buildExcShellViewExtensionMetadata(libConsoleCLI, aioConfig)
	payload.endpoints['dx/excshell/1'].view[0].metadata = metadata
	}

It is expected that cli plugin hooks (upcoming feature) will help with this.
