remotedialer: segfaults in sync.Pool when calling ClientConnect()

[zhucebuliaolongchuan]

Issue: PELEDGE19-3771 - edge-proxy has encountered segmentation fault during runtime due to third party package logrus used in remotedialer. Similar issue could be found here: golang/go#24640. While the issue happens within golang runtime and the problem has been unresolved even for the latest go release.

Potential solution: updating module logrus to v1.7.0 as it introduces a customized buffer pool API instead of using sync pool from native go lib. Details for the v1.7.0 release could be found here

Changes:

• Update go modules
• Change org name to new org name: armPelionEdge -> PelionIoT
• Fix Dockerfile build error

If you want to update just logrus you can use the following commands:

$ go get github.com/sirupsen/logrus@v1.7.0
$ go mod vendor

$ go get github.com/sirupsen/logrus@v1.7.0
$ go mod vendor

I just did this in #9
