Improve CatalogSource controller error handling during reconciliation

[everettraven]

Upon reconciliation of a CatalogSource resource, the CatalogSource controller does a few things:

• Creates a Job to unpack catalog contents
• Once unpack Job finishes, reads logs from the Job Pod to get the catalog contents
• Creates Package CRs for each package in the catalog
• Creates BundleMetadata CRs for each bundle in the catalog

Currently, the CatalogSource controller's error handling is very basic and should be updated to handle the following scenarios:

• IF the unpack Job can not be created
  • Update the CatalogSource resource status indicating the unpack failure
• IF the unpack Job's Pod's logs can not be read
  • Update the CatalogSource resource status indicating the unpack failure
  • IF the error is because the Pod no longer exists, requeue to attempt unpacking process again as the Job could have been cleaned up by another process
• IF a Package CR can not be created
  • IF caused by the Package already existing - continue
  • ELSE (?)
    • Update the CatalogSource resource status to indicate failure to create children resources
    • Cleanup already created child Package CRs
• IF a BundleMetadata CR can not be created
  • IF caused by the BundleMetadata already existing - continue
  • ELSE (?)
    • Update the CatalogSource resource status to indicate failure to create children resources
    • Cleanup already created children BundleMetadata & Package CRs

Note: All the scenarios here are just proposed solutions. Ones marked with (?) are ones I feel could have better solutions

catalogd v0.1.0 and OLMv1 M3 (operator-controller v0.1.0) were already released, so removing the olm-v1/m3 label and moving to the v0.2.0 catalogd milestone.

Looks like a lot of the to-do items mentioned above have been addressed in #65 and #83.

The only remaining issue that I can think of that hasn't been addressed yet is the atomicity of syncing Package/Bundlemetadata objects for a catalog that I've captured in #100
