What is your set up?

Self Hosted Docker

Is your feature request related to a problem? Please describe

Zapier integration is available for connecting github/gitlab/gitea et Al with Leantime.
As mentioned in #239 (comment)

But there is currently no easy way of doing this without using a 3rd party Host (Zapier) to achieve this.

Describe the solution you'd like

An idea would be to support Tools similar to Zapier. Tools like

Huginn:
https://github.com/huginn/huginn

Or:
https://github.com/n8n-io/n8n

as an example

n8n would be great. Unfortunately we don't have the resources right now to work on this. From what I understand it appears that it should be fairly straight forward since the endpoints that we use for zapier can also be used for n8n.
If someone from the community wants to take this on, I'd be happy to point them to the right methods.
