Add openssl_csr_info module (#54921)

* Add openssl_csr_info module.

* Make OpenSSL < 1.1 compatible.

* Simply remove signature algorithm.

* Adjust minimal version.

* Fallback code for some pyOpenSSL < 16.0 versions.

+module: openssl_csr_info
+version_added: '2.8'
+short_description: Provide information of OpenSSL Certificate Signing Requests (CSR)
+description:
+    - This module allows one to query information on OpenSSL Certificate Signing Requests (CSR).
+    - In case the CSR signature cannot be validated, the module will fail. In this case, all return
+      variables are still returned.
+    - It uses the pyOpenSSL or cryptography python library to interact with OpenSSL. If both the
+      cryptography and PyOpenSSL libraries are available (and meet the minimum version requirements)
+      cryptography will be preferred as a backend over PyOpenSSL (unless the backend is forced with
+      C(select_crypto_backend))
+requirements:
+    - PyOpenSSL >= 0.15 or cryptography >= 1.3
