update HANA and Netweaver/S4HANA password regex/docs

[melzer-b1]

update HANA and Netweaver/S4HANA password regex/docs for the following rules:

HANA:

• https://help.sap.com/docs/SAP_HANA_PLATFORM/009e68bc5f3c440cb31823a3ec4bb95b/974e9cb991704d05a256241a7b821971.html?locale=en-US&version=2.0.05
• https://help.sap.com/docs/SAP_HANA_ONE/102d9916bf77407ea3942fef93a47da8/61662e3032ad4f8dbdb5063a21a7d706.html?locale=en-US
• minimal_password_length = 8
• max length = 64
• The following character types are possible:
• Lowercase letter (a-z)
• Uppercase letter (A-Z)
• Numerical digits (0-9)
• Special characters (underscore (_), hyphen (-), and so on)
• Any character that is not an uppercase letter, a lowercase letter, or a numerical digit is considered a special character.
• The default configuration requires passwords to contain at least one uppercase letter, at least one number, and at least one lowercase letter, with special characters being optional.

Netweaver / S4HANA:

• https://help.sap.com/docs/SAP_NETWEAVER_750/c6e6d078ab99452db94ed7b3b7bbcccf/4ac3f18f8c352470e10000000a42189c.html?locale=en-US
• login/min_password_lng = 6
• max length = 40
• special characters are possible but not needed
• The password can only consist of digits, letters, and the following (ASCII) special characters: !"@ $%&/()=?'*+~#-_.,;:{[]}<>, and space and the grave accent.
• The password can consist of any characters including national special characters (such as ä, ç, ß from ISO Latin-1, 8859-1). However, all characters that aren’t contained in the set above are mapped to the same special character, and the system therefore doesn’t differentiate between them.
• no other restrictions

This PR will close #819

Hi,
the NetWeaver documentation says officially at least 3 characters as min.
https://help.sap.com/docs/SAP_NETWEAVER_750/c6e6d078ab99452db94ed7b3b7bbcccf/4ac3efb58c352470e10000000a42189c.html

But in general, your suggestion looks good to me. We may have to double-check if a long password with 20 digits or even longer would work with the SWPM. I still remember that it was not possible to use passwords longer than 16 digits.

The doc we linked in the issues tells us 3-40 chars are possible but 6 chars are the default value.

So I guess we're fine here.

That is definitively a check we should do before merging this.

LGTM now

AFAIK - For NetWeaver/ASCS/PAS the allowed master passwd length is 10-14 by SWPM and for HANA with higher number is allowed. Choosing "Custom" over "Typical" Parameter settings while running SWPM allows setting passwd for individual user (like TSMADM, WEBADM, SecureStorage, DB-Schema etc)
