- created class ExportSystemBulkAction in acc module
- Trying to get directory path from frontend

First export from the system achieved!

• First of all bulk action validate a given directory
• if the path does not exist, it will create it
• then because of multiselection of systems, it will also create a folder with a name of the system
• in that folder will file with name: <system-name><date><time-millis-of-day>.csv (SomeDifferentVirt2018-11-15-52111169.csv)

• header is created according to the schema of the system
• it will take all attributes of schema and creates a header

• then I handle objects in the system
• iterate header and if there is value, it will put it on a new line, if not then it will put an empty string inside
• multivalued attributes are separated by ","

• create ResultCode messages for some exceptions
• connect these messages with localization
• create test
• create documentation

- All messages in exceptions and names are in locates
- Exceptions are solved by ResultCode
- Test - creates a system, import accounts and export it - deletes all created files after
- Documentation - [[https://wiki.czechidm.com/tutorial/adm/systems_-_export_of_accounts_to_csv|here]]

- Also fixed counter problem in ImportFromCSVToSystemExecutor

• make DEFAULT_MULTIVALUED_SEPARATOR configurable (as "Separator of multivalued attributes"). The separator "," is not universal, e.g. when exporting AD, the values of groups contain "cn=groupname,ou=organization,dc=company,dc=tld". We would like to use "\n" (newline) for AD.
• (optional) make DEFAULT_LINE_SEPARATOR configurable (as "Attributes separator"). Although ";" is quite universal
• when the value contains " (double quote), it should be escaped by another double quote (escapechar in CSVWriter). Now it isn't escaped, which could cause some problems when parsing CSV.
• Description - change to "Export all accounts from system"
• file.getParentFile().mkdirs() - check the result. If false, return the ResultCodeException that the file cannot be created (same as when creating new file)
• Permissions - export shouldn't require SYSTEM_UPDATE, SYSTEM_READ should be enough. Please write the required permission to the wiki. (Note: when testing, there is a problem in permissions of bulk actions #1540)

• if there are some unresolved requests, the export has inconsistent data:
  • unresolved created accounts aren't exported -> correct
  • unresolved updates of accounts are exported already with the changes, which were not implemented yet -> problem, administrators would expect the real state on the system, which doesn't have the changes yet.
  • unresolved deletes cause NullPointerException. These accounts should be exported, because they were not deleted yet
  • after cancelling a delete request, the account is still exported -> correct
• when a new virtual system is created with a default role, "Behavior of the default role for inactive identities" must be set in the specific settings of the synchronization. Otherwise the synchronization doesn't start. Please set it to DO_NOT_LINK.
