cargo-shuttle: added beta deployment status

[iulianbarbu]

Description of change

Returns the list of all deployments sorted by updated_at column.
No pagination yet.
Will handle the ID for depl_latest as a reference to the latest running deployment, if any (it is just a partial replacement for cargo shuttle status for now).

How has this been tested? (if applicable)

Locally. Example cmd:

SHUTTLE_BETA=true cargo run -p cargo-shuttle -- --api-url http://iulian-control-alb-fae7fb2-914574683.eu-west-2.elb.amazonaws.com deployment status --wd examples/custom-resource/pdo/ depl_latest

Output:

Current deployment: 'depl_01HVM1YNS3VR0V5PKKT60Q3277' - running (http://pdo-yvm4dhkducmt.app.iulian.staging.shuttle.rs)
