ansible-test: async deployment w/ vcenter provider
So far, `ansible-test`'s vcenter provider was trigger by a blocking POST
call. Since the depoyment take a lot of time (> 8m), we decided to use
an async call instead and poll the API server until the deployment
is ready.
The vcenter provider allow one to use the `VMWARE_TEST_PLATFORM` to
manually select a test platform. The test platforms are:
- `govcsim`
- `static`
- and `worldstream`.
Before this commit, the `govcsim` value was ignored.
Example:
```shell
$ VMWARE_TEST_PLATFORM=govcsim ansible-test integration --python 3.7 needs/target/prepare_vmware_tests/
```
