Integrate pev2 as a component to vizualize execution plan

Could we add some text to explain what this does, what tool is used and maybe a link to PEV2? (not sure for the link)
I find the design a bit too minimalist :) .

I tried a sample plan coming from explain.dalibo.com (Example 5) and the visualisation seems broken. looks like js or css is missing.

C'est bon pour moi, à terminer avec pierre.

@marion, pourras-tu ajouter une entrée dans changelog ?

@MarionGiusti Can you please rebase your branch? pev2 requires bootstrap to be displayed correctly.

Maybe we should tell users what to do. There's no explanation about what this tool does and how to use it. No introduction text, nor placeholders in the textareas. For people who have already used explain.dalibo.com it will be straight forward, for others it will not.

In the pev2 projects, the release process is a bit random and there may be several versions released during one year. How will we make sure that we are up-to-date in temBoard?
