Without a libcurl built with the SSLS-EXPORT feature this command line
option produces:
curl: option --ssl-sessions: the installed libcurl version does not support this
curl: try 'curl --help' or 'curl --manual' for more information
Add a note of warning on the -ssl-session docs page to account for this.
Closes#17909
After Gmail called out the typo I fixed on
532d89a866, I've decided to paste the
whole man page into Google docs and check what other issues it would
spot.
I know, it sounds silly, but I've just spent the last hour and a half
going over each one of them and fixing everything which was a true
finding and non-controversial.
Closes#17480
Adds the experimental feature `ssls-export` to libcurl and curl for
importing and exporting SSL sessions from/to a file.

* add support in configure
* add support in cmake
+ add pytest case
Closes#15924
