This will cache the output of `passwordCommand` per authentication
realm.
Context: the `credentials` key in `sbt` is a `TaskKey[Seq[Credentials]]`.
In `sbt`, tasks are evaluated on-demand and their output is not cached.
This particular key is referenced by all submodules in a project. When
the command is relatively expensive (e.g.: `pass show foo`), this
results in several seconds of delay when doing basic things like
`compile` or `test` which makes this unusable without some kind of
caching.
sbt allows overriding the default repositories to use to resolve
dependencies. This is often used with proxies and/or private
repositories to host internal packages.
This change adds a `repositories` attribute to `sbt` to allow
specifying the values that will go in `~/.sbt/repositories` file.
To support the above change we also deprecate the `baseConfigPath`
option in favour of `baseUserConfigPath` which points one level higher
by default. This allows not using relative paths to refer to the
top-level configuration directory.
Also adds tests for the new option and the deprecation of the previous
one.
