OMHIREDIS::ADDED:: New support for 'stream' mode

 ### ADDED
- [OMHIREDIS] module is now able to insert entries to a Redis Stream
- [OMHIREDIS] in 'stream' mode, module can insert the message to a custom field in the entry ('msg' by default)
- [OMHIREDIS] in 'stream' mode, module can acknowledge an entry coming from imhiredis (if entry was claimed but not ACK'ed)
- [OMHIREDIS] in 'stream' mode, acknowledgements can be made from dynamic templates or static values
- [OMHIREDIS] in 'stream' mode, module can approximately cap the size of the output stream
- [OMHIREDIS] in 'stream' mode, module can delete an entry while inserting its message (useful to remove entry coming from another stream with imhiredis)
- [OMHIREDIS] new tests for 'stream' mode
 ### FIXED
- [CONFIGURE.AC] Missing line to give omhiredis compilation status
