test_wait_condition is failed due to domain name in endpoint

[Svetlana Shturm]

OSTF test_wait_condition is using script inside created VM that should use Heat API.
In using domain name case in endpoints (enabled SSL) this test will fail.
All curl execution inside VM with using domain name will be failed with unknown hostname message.

Steps to reproduce:
1) create env with enabled SSL (public endpoint),
2) execute Wait/Condition test.

Stack will be failed due to Timeout Error.

i will add "insecure" tag in template file.
This should solve the problem

[Svetlana Shturm (sshturm)]

Insecure flag is not enough. It will fail due to missing information about hostname.
In using SSL case keystone will return endpoint with domain name.
 Example: public.fuel.local.
Without records in /etc/hosts this name will be not resolved and your curl request will fail.
So insecure flag is only the part of needed changes. It will not fix problem with SSL at all.

We need to detect cluster public endpoint, get IP of the host and modify Heat template in OSTF test "on the fly" and add insecure flag to solve the issue.

Now heat team commited fix for ssl.
Need edit test template
