+ Generate a new password based on masterPassword. The new password is not
+ random, it is derived from masterPassword, fully qualified chart name and
+ additional uid provided by the user. This ensures that every time when we
+ run this function from the same place, with the same password and uid we
+ get the same results. This allows to avoid password changes while you are
+ doing upgrade.
+
+ The function can take from one to three arguments (inside a dictionary):
+ - .dot : environment (.)
+ - .uid : unique identifier of password to be generated within this particular chart. Use only when you create more than a single password within one chart
+ - .strength : complexity of derived password. See derivePassword documentation for more details
+
+ Example calls:
+
+ {{ include "common.createPassword" . }}
+ {{ include "common.createPassword" (dict "dot" . "uid" "mysqlRootPasswd") }}
