Clean up task log entries by removing some configuration paths

[prioux]

Whenever anything is logged in a task's log, we should remove the constant paths that match configuration settings, such as the gridshare path or the DP cache path.

So, a task log entry that now looks like:

[2023-03-27 18:42:27 EDT] make_cluster_workdir() Trying to create workdir '/scratch/prioux/BourreauBeluga/GridShare/224/06/57/blah-FMRIprepBidsSubject-T2240657'.

would instead be logged as:

[2023-03-27 18:42:27 EDT] make_cluster_workdir() Trying to create workdir '224/06/57/blah-FMRIprepBidsSubject-T2240657'.

Given the CbrainTask class already has an overriden version of hte method 'addlog', it should be an easy fix to zap these things before actually logging:

cbrain/BrainPortal/app/models/cbrain_task.rb
