Description of problem:
When running 'hammer import all' multiple times
(1st pass to trigger repository sync, 2nd pass to create content views, ...)
the 'hammer import user' complaints about password file being already created.
Since this is a recommended use case, hammer import should count with that and shall not complain.
If password file already exists, just append eventual new lines.
(in 99% cases all users will be created during the 1st pass and no append will happen anyway.)
*** Bug 1130478 has been marked as a duplicate of this bug. ***
It would be nice if ".<n>" would be appended for least natural n such that
desired filename does not exist in case requested file exists.
This solution might be proffered as simply appending existing csv (or any other file) might lead to some complications (say in case users were deleted and re-imported, there will be two entries for the same user in single file).
Actually this is no issue to 'hammer import all' command, closing as NOTABUG.
