Use the latest EDM version (3.0.1)

[rahulporuri]

A new major version of EDM is available and it would be good to update to the latest version - https://assets.enthought.com/downloads/edm/. This should be as simple as updating the environment variables in travis and appveyor config files.

enable/.travis.yml

Line 23 in 6cf525c

- INSTALL_EDM_VERSION=2.0.0

enable/appveyor.yml

Line 8 in 6cf525c

INSTALL_EDM_VERSION: "2.0.0"

Note that there is a major behavioral change with version 3.0.1 of EDM - the default platform tag used on unix is rh7, not rh6. Previously, users needed to explicitly pass the rh7 platform cmdline flag if they wanted to created an rh7 environment and rh6 was the default if no flag was set.

We weren't setting this flag earlier -

enable/ci/edmtool.py

Line 157 in 6cf525c

"edm environments create {environment} --force --version={runtime}",

When we update edm to version 3.0.1, we will automatically switch to using the rh7 environments + rh7 packages in the environments instead of rh6. This should not break anything but we need to be aware of this change.

FYI, this is not exactly true. EDM 3.x will use as default platform rh6 or rh7 based on the libc version of the system. On old systems rh6 will be the default while on more recent systems it will be rh7.
