* Added startup error for bad temporary directory setting.
If the temporary directory (--temp.path) setting is identical to the database
directory (`--database.directory`) this can eventually lead to data loss, as
temporary files may be created inside the temporary directory, causing overwrites of
existing database files/directories with the same names.
Additionally the temporary directory may be cleaned at some point, and this would lead
to an unintended cleanup of the database files/directories as well.
Now, if the database directory and temporary directory are set to the same path, there
will be a startup warning about potential data loss (though in ArangoDB 3.4 allowing to
continue the startup - in 3.5 and higher we will abort the startup).
* make TTL indexes behave like other indexes on creation
if a TTL index is already present on a collection, the previous behavior
was to make subsequent calls to `ensureIndex` fail unconditionally with
the error "there can only be one ttl index per collection".
now, we are comparing the attributes of the to-be-created index with the
attributes of the existing TTL index and make it only fail when the
attributes differ. if the attributes are identical, the `ensureIndex`
call succeeds and returns the existing index.
