* Fixes for Alloydb E2E tests
* too long project name in Sipmle example resulted in:
```
Error: "***-alloydb-prj" name must be 4 to 30 characters with lowercase and uppercase letters, numbers, hyphen, single-quote, double-quote, space, and exclamation point.
```
* using self_link resulted in:
```
Error: Error creating Cluster: googleapi: Error 499: malformed network path: "https://www.googleapis.com/compute/v1/projects/***/global/networks/e2e-test"
```
* Cross region replication stil fails with:
```
│ Error: Error creating cluster. Can not create secondary cluster without secondary_config field.
│
│ with module.alloydb.google_alloydb_cluster.secondary[0],
│ on /usr/local/google/home/wiktorn/git/cloud-foundation-fabric/modules/alloydb/main.tf line 199, in resource "google_alloydb_cluster" "secondary":
│ 199: resource "google_alloydb_cluster" "secondary" {
```
* Fix tests
