[ENH] - Improved checks on projectname during init stage

[kcpevey]

Feature description

My qhub projectname that I used when I ran qhub init included an underscore. This was the error that was generated when I went on to qhub deploy:

[terraform]: │ Error: "name" can only contain lowercase letters, numbers and hyphens
[terraform]: │
[terraform]: │   with module.kubernetes.google_container_cluster.main,
[terraform]: │   on modules/kubernetes/main.tf line 5, in resource "google_container_cluster" "main":
[terraform]: │    5:   name     = var.name
[terraform]: │
[terraform]: ╵
[terraform]: ╷
[terraform]: │ Error: "account_id" ("this_deployment-dev") doesn't match regexp "^[a-z](?:[-a-z0-9]{4,28}[a-z0-9])$"
[terraform]: │
[terraform]: │   with module.kubernetes.google_service_account.main,
[terraform]: │   on modules/kubernetes/service_account.tf line 2, in resource "google_service_account" "main":
[terraform]: │    2:   account_id   = var.name
[terraform]: │
[terraform]: ╵

1. the error comes from a subsequent step in the project (init vs deploy)
2. the error mentions name but the variable that I set was projectname

These things make it misleading for users to debug.

I recommend that the init stage have a check to ensure that it passes the required restrictions and provides reasonable feedback when it doesn't

Value and/or benefit

users who are not confused at failures.

Anything else?

@iameskild and @asmijafar20 this should be good to implement in the CLI work

Hi @trallard, this check has now be incorporated into the init command 🙌

This issue is a subset of the items that need to be validated when initializing the qhub-config.yaml.

Completed as part of new Nebari CLI 🤘
