Rather than removing the previous implementation of SanitizeLabelName,
offer another version named SanitizeFullLabelName that achieved the
desired requirements, without breaking existing Prometheus code.
Update testing to validate correctness of new variant.

SanitizeLabelName was not correctly sanitizing label names that:
1. Started with a digit (0-9)
2. Were empty
This commit changes the santization code to catch both of these edge
cases and adds new tests to validate it works correctly in them both. In
the first case, a leading digit will be replaced with an underscore, and
in the latter, the function will return a single underscore.

This reverts commit aa43d34a86.
This brings back the /graph changes so that @grandbora can continue to
work on the redirect for backwards compatibility. And other changes
can already take the new /graph parameters into account.
This revert will be reverted once v1.1 is released and has its own
release branch. Since we had already change on top of this, there was
no cleaner way of cutting those changes out.
This commit reverts the following commits:
Revert "Update backend helpers and templates to new url schema"

Revert "Point to correct place for GraphLinkForExpression"
This reverts commit 3da825fc76.
Assets are also updated.
It's actually happening in several places (and for flags, we use the
standard Go time.Duration...). This at least reduces all our
home-grown parsing to one place (in model).
