🎨 v2.6.17 Enhance pipeline editing, fix dropping pipes with custom schema.

[bmeares]

v2.6.17

• Add relative deltas to starting in scheduler syntax.
  You may specify a delta in the job scheduler starting syntax:

  mrsm sync pipes -s 'daily starting in 30 seconds'
  

• Fix drop pipes for pipes on custom schemas.
  Pipes created under a specific schema are now correctly dropped.

• Enhance editing pipeline jobs.
  Pipeline jobs now provide the job label as the default text to be edited. Pipeline arguments are now placed on a separate line to improve legibility.

• Disable the progress timer for jobs.
  The sync pipes progress timer will now be hidden when running through a job.

• Unset MRSM_NOASK for daemons.
  Now that jobs may accept user input, the environment variable MRSM_NOASK is no longer needed for jobs run as daemons (executor local).

• Replace Cx_Oracle with oracledb.
  The Oracle SQL driver is no longer required now that the default Python binding for Oracle is oracledb.

• Fix Oracle auto-incrementing for good.
  At long last, the mystery of Oracle auto-incrementing identity columns has been laid to rest.
