Improve storage item scriptlets — add regexp support for items removing

[Alex-302]

• add ability to remove a key
• add regex suppot for matching keys, which have variable part(for example mp_***_mixpanel, generated by Similarweb browser extension)

[slavaleleka]

for removing the key we may consider adding a new scriptlet

@stanislav-atr Any news?)

[slavaleleka]

ability to remove an item from the storage is implemented already: #338

but it looks like there is no way to get all storage keys so scriptlet shall not be able to match the needed ones by the regexp. it means that it's impossible to improve the current implementation and make regular expressions acceptable for storage items removing

[AdamWr]

Couldn't we use something like Object.keys(localStorage) and then iterate it to check if it contains a specific key which would be matched by regexp?

[slavaleleka]

you're right, we can try that
