Add Optional IGNORE Clause for Time Series Commands

[ofekshenawa]

Description:
This issue introduces an optional IGNORE clause for Time Series commands to filter close samples. The IGNORE clause includes two parameters: IGNORE_MAX_TIME_DIFF (milliseconds) and IGNORE_MAX_VAL_DIFF (floating-point). These parameters can be used in the TS.CREATE, TS.ALTER, TS.ADD, TS.INCRBY, and TS.DECRBY commands.

Requirements:

1. IGNORE Clause Parameters (R.1)

   • IGNORE_MAX_TIME_DIFF: Max time difference between samples.
   • IGNORE_MAX_VAL_DIFF: Max value difference between samples.

2. TS.CREATE (R.1.1)

   • Support IGNORE clause parameters.
   • Example: TS.CREATE ... IGNORE <ignore_max_time_diff> <ignore_max_val_diff>

3. TS.ALTER (R.1.2)

   • Support IGNORE clause parameters.
   • Example: TS.ALTER ... IGNORE <ignore_max_time_diff> <ignore_max_val_diff>

4. TS.ADD (R.1.3)

   • Support IGNORE clause parameters.
   • Example: TS.ADD ... IGNORE <ignore_max_time_diff> <ignore_max_val_diff>

5. TS.INCRBY (R.1.4)

   • Support IGNORE clause parameters.
   • Example: TS.INCRBY ... IGNORE <ignore_max_time_diff> <ignore_max_val_diff>

6. TS.DECRBY (R.1.5)

   • Support IGNORE clause parameters.
   • Example: TS.DECRBY ... IGNORE <ignore_max_time_diff> <ignore_max_val_diff>
