feature: progress bar in context menu's metadata

[szymczakovv]

On each metadata item you can set progressbar also you can still set value (not required) like this;

{
    ["label"]: "Body",
    ["value"]: "55%",
    ["progress"]: 55
}

or just like this;

{
    ["label"]: "Oil",
    ["progress"]: 11
}
