[CLOSED][VOTE] Remove check for passwords that prevents using only whitespaces

Hi everyone,

we currently have a very old check in XWiki standard when new users registered that prevents them to use only whitespaces as password.
This check can be found there: https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwiki-platform-oldcore/src/main/java/com/xpn/xwiki/XWiki.java#L3869.
IMO it does not make sense anymore since we now have password security policies that can be enforced, as part of https://jira.xwiki.org/browse/XWIKI-11309

So I propose to now remove this old check from our code.

The vote will be open until the end of next week: friday 07/11, and here’s my +1.

So, on 5 committers vote, 5 +1. I’m closing the vote now.
I will remove the check as announced and close the related issue. Thanks everyone.
