fix: Master password autogen constraints to match AWS requirements

[leondkr]

Description

The issue is mentioned in #71 Basically, when specifying the master_password, AWS has constraints that

• Must be between 8 and 64 characters in length.
• Must contain at least one uppercase letter.
• Must contain at least one lowercase letter.
• Must contain one number.
• Can be any printable ASCII character (ASCII code 33-126) except ' (single quote), " (double quote), , /, or @.

Currently, we have the attribute min_special (sets as 1) which overrides the special (sets as false) and randomly assigns the constraints characters as mentioned above.

Motivation and Context

We want to use the built-in attribute create_random_password without having our custom random_password resource.

Breaking Changes

It does not break any backwards compatibility as master_password is currently under lifecycle's ignore_changes.
