  Purpose

• When using the deploy script found at single_tech_samples/synapseanalytics/sample1_loading_dynamic_modules/setup I am sometimes getting the following error:

  (ValidationFailed) Workspace request validation failed, check error details for more information
  Code: ValidationFailed
  Message: Workspace request validation failed, check error details for more information
  Exception Details:  (InvalidSqlServerPassword) Sql Server password not complex. The password must be atleast 8 characters long and contain characters from three of the following four categories: (uppercase  letters, lowercase letters, digits (0-9), Non-alphanumeric characters such as: !, $, #, or %).
  Code: InvalidSqlServerPassword
  Message: Sql Server password not complex. The password must be atleast 8 characters long and contain characters from three of the following four categories: (uppercase  letters, lowercase letters, digits (0-9), Non-alphanumeric characters such as: !, $, #, or %).

• This is caused by the command generating the password: SQL_ADMIN_PASSWORD=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 15 | head -n 1 | tr '[:upper:]' '[:lower:]' )!
• Since the input is completely random there is a non-zero chance that the password will not contain a number. Since we are converting all upper case to lower case then it leads to sometimes the password only having lowercase letters and an ! which means it fails the complexity check.
• Can be fixed by removing tr '[:upper:]' '[:lower:]' from the command

Does this introduce a breaking change? If yes, details on what can break
