[BUG] availability zones are hard coded to us-east-1 values

[DataBoyTX]

Describe the bug
the region is a terraform variable the user can set in terraform.tfvars (misnamed "availability_zone_name", should likely be changed to region for clarity), but if you switch something other than the default of us-east-1, that results in several errors similar to the below, because the azs are hardcoded to us-east-1x azs

graphistry-helm/terraform/aws/main.tf

Line 95 in 9a987b4

azs = ["us-east-1a", "us-east-1b", "us-east-1c"]

│ Error: error creating EC2 Subnet: InvalidParameterValue: Value (us-east-1a) for parameter availabilityZone is invalid. Subnets can currently only be created in the following availability zones: us-east-2a, us-east-2b, us-east-2c.
│ 	status code: 400, request id: f1c03dc3-e39b-49ab-8985-f3ff04673721

│   on .terraform/modules/vpc/main.tf line 350, in resource "aws_subnet" "public":

│

To Reproduce
change the region to something other us-east-1 in terraform.tfvars and run terraform plan or apply

Expected behavior

• rename availability_zone_name to region in terraform.tfvars, vars.tf and align in main.tf
• add availability zones to vars.tf, terraform.tfvars or come up with an alternative to hard coding the values

Actual behavior

results in errors like:

│ Error: error creating EC2 Subnet: InvalidParameterValue: Value (us-east-1a) for parameter availabilityZone is invalid. Subnets can currently only be created in the following availability zones: us-east-2a, us-east-2b, us-east-2c.

│   on .terraform/modules/vpc/main.tf line 350, in resource "aws_subnet" "public":
│  350: resource "aws_subnet" "public" {

Yea iirc I couldn't add a var right there but will check agn thx!

Or actually I think it was I thought it redundant to have to specify az by just us east , and then subnet in a diff var so I thought verbosity here made more sense
