The following retention policy commands in influxdb-python/influxdb/client.py do not escape/backtick database and/or retention policy name thus breaking when allowed characters are used elsewhere (e.g. database names containing hyphens like "db_0474102f-8397-481d-bcba-06f3a682854d").

Note: This might extend to more than simply retention policy commands but will allow maintainers to determine scope as it should be universally done.

1. create_retention_policy

   
      query_string = \
           "CREATE RETENTION POLICY %s ON %s " \
           "DURATION %s REPLICATION %s" % \
   
   

2. alter_retention_policy

   
       query_string = (
           "ALTER RETENTION POLICY {0} ON {1}"
   
   

3. drop_retention_policy

   
       query_string = (
           "DROP RETENTION POLICY {0} ON {1}"
   
   

4. get_list_retention_policies

   
       rsp = self.query(
           "SHOW RETENTION POLICIES ON %s" % (database or self._database)
