Errbit exits without clearing outdated/resolved if COMPACT command is not permitted to use

[gavindsouza]

Step 1: Are you in the right place?

I have a suggestion to run database compact only if allowed. Opened this issue since I think this has not been addressed before.

Step 2: Describe your environment

• Errbit version: 0.10.0-dev
• OS: heroku-20

Step 3: Describe the problem:

Running rake errbit:clear_outdated creates ProblemDestroy objects but fails on compact_database step while using MongoDB Atlas free tier with [8000:AtlasError]: CMD_NOT_ALLOWED: compact (on errbit-shard-YYYYY.XXXXX.mongodb.net:27017)

Expected Results:

Print a warning to STDOUT that not enough perms for COMPACT; Skipping. The job completes successfully and the Problems are destroyed.
