Generate alias file

[bomoko]

This introduces a command to generate a file of aliases - this is particularly useful when dealing with sites that live on separate clusters when accessing via the ssh-portal

[bomoko]

Thanks @tobybellwood - should all be sorted now

[tobybellwood]

we need to handle existing deploytargets here that have no specific ssh host set - otherwise they will return null as the host?

I'm just not sure where to read it from - we could fall back to the lagoon aliases (or a hard coded default?

[bomoko]

@tobybellwood - I think that should do it.

[tobybellwood]

to accommodate uselagoon/build-deploy-tool#193

Suggested change

	$this->api = $lagoonyml['api'] ?? 'https://api.lagoon.amazeeio.cloud/graphql';
	$this->api = getenv('LAGOON_CONFIG_API_HOST') ?? $lagoonyml['api'] ?? 'https://api.lagoon.amazeeio.cloud/graphql';

[tobybellwood]

we'd ideally make a function here to handle uselagoon/build-deploy-tool#193 and fallback defaults to use in a chained null coalesce as per the api. We can probably assume that the last chance fallback doesn't need to be host and port configurable though?
