Create all Azure resource in the same region of the resource group

[petetian]

Purpose

• ...
  create-azure-resources.sh was choosing SQL, AI and GRAFANA LOCATION randomly, which may allocate these resources in different locations. Having discussion with course leaders, the consensus is that resource group location can be random, but the resources within the resource group should be in the same location, to avoid network latency.

Minor change in azure-resource.profile: add instruction taken from learner's manual as comment, including generate unique-id, and query azure subscription-id in comments, for learner's reference

'petclinic' -> '$APPNAME'

[sonwan2020]

when multiple members share the same subscription, this would cause some conflicts on same resource group.

[sonwan2020]

same for the acr, aca environment list & check

[sonwan2020]

renew the UNIQUEID will cause mismatch in the later steps.

[sonwan2020]

Here are the problems with these regions:

1. OpenAI not supported in eastasia
2. Managed Grafana not supported in southindia, prefer use centralindia
   See the differences between AI_LOCATION, SQL_LOCATION, GRAFANA_LOCATION

[sonwan2020]

BTW, I don't think the potential regional latency is matter in this lab environment

[sonwan2020]

Please sync the latest code and pay attention to my previous comments

[selvasingh]

@sonwan2020 and @petetian request you to advance and merge this ASAP. Mark Heckler ran into similar challenges

[sonwan2020]

@selvasingh which challenge do you refer to?

1. I had an agreement with Pete, his PR won't change the process to end users.
2. Some issues mentioned in this PR, I already fixed with other PRs.

[petetian]

@sonwan2020: please review the PR. Thanks!

[sonwan2020]

in some environment like Github codespace, we may fail to get the AAD_USER_ID, we should check if the AAD_USER_ID is valid before continue

[sonwan2020]

replace the petclinc to $APPNAME

[sonwan2020]

we will have user to set the UNIQUEID in profile and import those settings first.
we run "export RESOURCE_GROUP=rg-$APPNAME-$UNIQUEID" at the beginning.

In the current process,

1. there will be conflict on resource group name
2. we make sure we can rerun the script

[sonwan2020]

we may ask user to input the subscription.

az account set -s SUB

or az configure --default subscription=xxx

[sonwan2020]

I prefer this way: user set the unique id in profile and we use the id for new resources

[sonwan2020]

I am OK about the scripts, but I am concerned about the process. let me have another discussion
