Previously if there were any “pin” updates then that would block all non-pin updates until the pin one was merged. However, this doesn’t make sense if the other PR is for an unrelated dependency.

Closes https://github.com/renovatebot/config-help/issues/64

Adds support for PIP_INDEX_URL from environmental variables for self
hosted version. This is used instead of any urls set in the config.

This should address the GITHUB_ENDPOINT problem in #2249

Closes #2246

Closes https://github.com/renovatebot/config-help/issues/63

This reverts commit 247bdf6b.

Refactors template logic to test for isSingleVersion instead of the negative of isRange. This means that new values like `==1.2.0` in python will be presented as v1.2.0

If an encrypted npmToken is found alongside an unencrypted npmrc in config, then the token will replace any `${NPM_TOKEN}` placeholder found, or be appended to the end of the file. This enables large npmrc files to be defined in config without needing to enrypt the entire thing.

Closes #1796
