Create security groups with given resource group

[rsrchboy]

...much as we do elsewhere, if the configuration specifies a resource group, honor it and use it to create security group.

Note that the lack of this is causing issues when blanket permissions are not granted to the default resource group, e.g.

2023-01-04T20:40:53Z: ==> ibmcloud-vpc.base: [ERROR] Error creating the Security Group. Error: user does not have permission to use default resource group
2023-01-04T20:40:53Z: ==> ibmcloud-vpc.base: [ERROR] Error creating a Temp Security Group: [ERROR] Error creating the Security Group. Error: user does not have permission to use default resource group

Hi @rsrchboy Thank you for your contribution. Build failure is due to Docker - creds are not available for builds on forked repos. I'd request you to create a branch in this repo directly. Thanks.

@astha-jain I'm not opposed to pushing directly, but currently I lack the permissions :)

ERROR: Permission to IBM/packer-plugin-ibmcloud.git denied to rsrchboy.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
