Add source parameter to user resource

[Edu-DevOps]

Issue detailed here: #371 (comment)

In a nutshell, without the source parameter two users (one local and one LDAP) can collide using the same userid.

I've updated documentation and run tests successfully.

This is a test done in a local environment:

Terraform will perform the following actions:

  # nexus_security_user.test will be created
  + resource "nexus_security_user" "test" {
      + email     = "[email protected]"
      + firstname = "Test"
      + id        = (known after apply)
      + lastname  = "User"
      + password  = (sensitive value)
      + roles     = [
          + "nx-admin",
        ]
      **+ source    = "default"**
      + status    = "active"
      + userid    = "test-user"
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value: yes

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

And this is a state show of the object

terraform state show nexus_security_user.test
# nexus_security_user.test:
resource "nexus_security_user" "test" {
    email     = "[email protected]"
    firstname = "Test"
    id        = "test-user"
    lastname  = "User"
    password  = (sensitive value)
    roles     = [
        "nx-admin",
    ]
    source    = "default"
    status    = "active"
    userid    = "test-user"
}

Taken advantage of the PR I've fixed the examples/local-development/main.tf file which was using a resource that doesn't exist

I dont have an LDAP setup to test against at this time, but i suspect you cannot create LDAP users in this way? When i try to create a user with source LDAP, the api returns a user with source "default".

If it is not possible to create LDAP users this way, I would suggest removing the possibility to set the source here, or the possiblity to set anything other than default.

That's actually right, LDAP users aren't created by Nexus in this way. I'll remove the posibility to set other than default just in case in the future another source spawns in a Nexus release.
