Add ignoreAttribute option

[darcros]

I am using this plugin with React and Typescript and I have found it very useful so far.
However, I think it would be useful to add an ignoreAttribute option, similar to ignoreCallee but for JSX attributes.

The reason is:

<TextField
  variant="outlined"
  margin="normal"
  name="newEmail"
  autoComplete="email"
/>

TextField from material-ui

In the example above variant and margin are not reported as errors because their types are defined as a an union type of different strings.
But name and autocomplete are of type string so they get reported.

An ignoreAttribute option is necessary because the other solution would be spamming every file with eslint-disable-next-line comments.
And adding other attributes to the whitelist (like has been done with #4) for every framework and library that comes along would just be unfeasible.

I could work on the PR myself, just need to know if you would merge it.

It's great. I think there are some cases that UPPERCASE and union type of strings cannot handle in an instinctive way.

Expect your PR.
