This reapplies commit 4bfa135b [1]
which got reverted in commit 1b59c19a
[2] due to issues in how TripleO Quickstart installed the Ansible
OpenStack collection. TripleO Quickstart has now been fixed and
will install code from our stable/1.0.0 branch instead of master for
all RDO branches which have openstacksdk <0.99.0 [3][4].

This reverts commit 4bfa135b [1] because
it broke TripleO [2] and possibly other users which were using code from
master branch with incompatible SDK releases. We will reapply this
safety check later once dust has settled.

Alongside OpenStack SDK 1.0.0 we will release a new collection version
2.0.0 which is compatible to OpenStack SDK 1.x.x series only. Code in
branch stable/1.0.0 will remain compatible to OpenStack SDK 0.x.x
series only. Release candidates for the first major release of
OpenStackSDK 1.x.x will be numbered using 0.99.x versions.

At Ansible OpenStack modules PTG on 2022-04-07 it was decided to raise
an error if one is using a incompatible releases of the OpenStack SDK
with our collection. We decided against showing warnings only because
they can be missed easily and functionality  will be broken but
probably hardly detectable when using the wrong SDK.

This patch bumps the minimum required SDK versions to 0.99.0, so that
an error will be raised when users try to use our collection with an
incompatible SDK release, e.g. use code from our master branch with
a OpenStack SDK 0.x.x release.

For example, to_dict's computed parameter is available since
SDK 0.18 (Stein) only.

Overview on OpenStack SDK versions in various distributions:
* ArchLinux has SDK 0.59.0
* CentOS 7 has SDK 0.36 (Train)
* CentOS 8 has SDK 0.36 (Train), SDK 0.46 (Ussuri),
  SDK 0.50 (Victoria) and SDK 0.55 (Wallaby)
* Debian 10 (Buster) has SDK 0.17.2 and Ansible 2.7.7 which
  does not support Ansible collections anyway. Debian's
  buster-backports repository has Ansible 2.9.16 but backports
  are provided on an as-is basis, with risk of incompatibilities.
* Debian 11 (Bullseye) has SDK 0.50.0
* Ubuntu 18.04 LTS has SDK 0.11.3 which is not supported by
  this collection since the lowest supported version so far
  is 0.13
* Ubuntu 20.04 LTS has SDK 0.46.0
* Red Hat OpenStack (RHOSP) 16.0-16.2 have SDK 0.36 (Train)
