Some configuration options started with a capital letter indicating the beginning of a sentence, which didn't makes sense without the colons. Similarly, some were missing periods at the end of their descriptions. [ci skip]

Active Job: Add note about ability to configure adapters on per job basis in CHANGELOG and release notes

[FIX] Change 1.week to create 1 week durations instead of 7 days durations.

Remove last uses of `@env[]` and `@env[]=`

Active Job: Add note about ability to configure adapters on per job basis in CHANGELOG and release notes.

[ci skip]

Last August (2015), @tenderlove worked to remove all `@env[]` and `@env[]=`, in
favor of using `set_header`, `get_header`, etc. (Here's an [example
commit](https://github.com/rails/rails/commit/f16a33b68efc3dc57cfafa27651b9a765e363fbf)).

This PR should remove the last uses of these methods, and fully convert
them to the newly standardized API.

schema_load triggers 2nd schema_load (via locking)

Currently, loading the schema (schema_load)
accesses the locking column (locking_column)
which defaults the value (reset_locking_column)
which invalidates the schema (reload_schema_from_cache)
which forces another schema load.

Good news:
The second schema_load does accesses locking_column,
but locking_column is set, so it does not reset_locking_column
and it does not trigger an infinite loop.

The solution is not invalidate the cache while default locking_column

Push action_view.collection_caching to be called towards the end

Push action_view.collection_caching to be called towards the end, since it depends on being called after action_controller.set_configs.
This causes, other AV initializers after it to be called after all of AC initializers, which get pulled in before since action_controller.set_configs gets called.
Hence, push initializer depending on after hook, to be called after all initializers for this railtie are done.

This addition of `--pre` fixes the issue we were seeing when installing
a local copy of a pre-release rails version.

We don't need no stinking `on_load` where we're going! Because
people far wiser than me (@rafaelfranca and @jeremy) know that
passing `:after` means the lib is already loaded.

I always appreciate having a bit more information as to why something is
now an error. We can use this error to tell people why what they were
previously doing is insecure and give them hints on how to fix it.
