file name format update for sqlbackup script

[anonyme]

I've patch the sqlbackup.sh script few month ago to change the file name format for sql backup.

Instead of using a "logrotate" format such as file.X.sql, it's possible to include the date of the day in the file name like file.YYYYMMDD.sql

this option is useful when you backup alternc/html with rsync to avoid rsync all backup file after each backup name rotation.

(In [2257]) complete rewrite of the sqlbackup.sh script, will be reworked and audited before release

Closes: #1081

(In [2259]) add some of the sqlbackup options to the local.sh global configuration. note that we discarded some suggestions options:

F_LOG: replaced with syslog DAEMON: will be considered for inclusion later VERBOSE/DEBUG: available through command line flags

TYPE_NAME_BACKUP and ALLOW_OVERWRITE_BACKUP are being renamed to SQLBACKUP_TYPE and SQLBACKUP_OVERWRITE. this is to be more consistent with the global configurations

See: #1081

I should also mention commit [2258] which gets rid of the F_LOG option. I will work a bit more on the code now.
